AIR PREHEATER

Enerfin-inc.com sells air preheater. The air preheater is a static type with cast iron fin tube in the upper section and glass tube in the lower section. We recently were asked our thoughts regarding whether it was worthwhile to consider replacing an old steam air preheater with one of today's new designs.

If you already have a furnace or boiler with an older steam air preheater supplier, and are looking for improvement, you may have some air preheater options.

The possibility of fire in an steam air preheater increases if one air preheater is shared with multiple furnaces. The bottom line is that both types of air preheaters have offsetting advantages and disadvantages. There have been little design changes in recent years, which have increased air preheater manufacturer efficiency.

In addition to the above parameters other parameters can also be calculated: for example air preheater effectiveness, air preheater leakage, and flow rate of emissions such as CO 2 and SO 2.

The hot gas flowing through the uniflow cyclone is cooled in the air preheater before it is fed into the main boiler. The gasification air is heated in the air preheater before it is fed to the gasifier. The low-Btu gas from the gasifier is led directly from the cyclone through the air preheater to two burners that are located below the coal burners in the boiler.

Other important inventions include the turbine-powered locomotive and the "air preheater". The American Society for Engineering Management designated the Ljungström regenerative air preheater an "International Historical Mechanical Engineering Landmark," calling it one of the greatest mechanical inventions of all time.

The smokebox contained a rotating-media air preheater warmed by the flue gases. The funny sector-shaped thing on the front of the smokebox is the drive to the friction rollers that rotated the air preheater. This renders the original air preheater unnecessary, so it would be removed and the heat it normally recovers from the flue gases before the stack would become available. This heat can be recovered by new economisers installed in place of the original air preheater.
Enerfin Shell and Tube (S & T) heat exchangers are custom designed and manufactured to the latest edition of ASME Sect VIII Div. 1 and TEMA Standards to satisfy any requirements. Enerfin can provide shell and tube heat exchangers in a variety of material such as carbon steel, stainless steel, cu/ni 90/10, titanium, incoloy and others. Enerfin is a shell and tube manufacturer.

Maximum surface per given shell and tube size for removable bundle designs. Shell and tube heat exchangers are among the more confusing pieces of equipment for the process control engineer. There are a number of varieties of the basic shell and tube exchanger that can be controlled along similar lines.

Aerial coolers, sometimes called fin fan coolers, are similar to shell and tube exchangers except that they are all tube. As mentioned earlier, aerial coolers can be considered a special type of shell and tube exchanger in which the shell is the shell of the cooler. Overpressure is the only common safety issue affecting shell and tube heat exchangers.

Enerfin manufacturers a complete line of Shell & Tube Heat Exchangers for both Fresh Water and Salt Water applications. These guidelines have been written primarily for application to shell and tube heat exchangers for service offshore on the shelf.

Using quick connect hoses, and the optional trailer, your Heatsink transformer cooler can be transferred easily. The air cooled oil coolers are designed to dissipate heat from the oil of generator Transformer cooler.

Similarly in transformer coolers are used to cool transformer oil by air or water. These transformers coolers play an important role in smooth functioning of main equipments.
An efficient transformer cooler manufacturer will loose less power through heat and operate at a cooler temperature.

he purpose of the gland steam condenser is to reduce steam leakage to a minimum and to prevent air ingress. The gland steam condenser is cooled by the condensate extracted from the main condenser and so acting as a feed heater.The steam gland condenser often shares its condenser with the air ejector reducing the cost of having two units.

With the condenser under a vacuum, this cooling water condenses the exhaust steam packing and then to a line leading to the steam gland exhaust condenser.
In addition to appropriate packing, as part of our steam sealing systems we provide our turbines with a steam gland condenser system. Enerfin's standard scope of supply includes leakoff manifold, steam gland condenser, air ejector and condensate tank.

The conservation of auxillary boiler steam strictly for process steam supply and thus eliminates need for steam supply to the steam gland condenser seals. The engine is stopped the gland steam condenser make-up supplies the system requirements.


There are two pockets in the glands fitted to all the ends of the turbine and the inner pocket is connected to the steam gland condenser manufacturer and the outer to the exhaust line.
Enerfin industrial steam coils can be supplied in a self supporting frame in which pull out drawer type steam coils can be serviced individually. Our standard non-freeze steam coil is designed to handle large amounts of steam and provide quick condensate removal.

The two sources of acidic corrosion in the steam coils air heater will be carbonic acid, source is CO2 in the water and oxygen attack. A material that can be used for steam coil tubes manufacturer when the steam pressure is above 200 psig. During this condition, air is bypassed around a steam coil when full steam flow is used in the coil. Steam coil information available by clicking above.

Our low-pressure steam coils are carefully designed to withstand the rigors of this application. Minimum tube wall thickness on a steam coil is .025". .035" wall thickness is available if required. When it comes time to replace an old steam coil that's corroding and cracking like an old pickup truck.

First, determine what type of steam coil you are replacing. Is it standard steam, nonfreeze steam, hot water, hot oil, hot gas or other heat transfer fluid that is heating the fin-side gas ?

However, two recent projects showed that the traditional process isn’t the only process for replacing steam coils.D uring this period other companies have supplied custom-made flat pans and steam coils on a limited basis.

To assess the effectiveness of the coated hydrogen cooler, the tube ID of one hydrogen cooler was glass beaded until all scale and corrosion products were removed and another was coated with Enerfin coating system and proprietary coating materials.

From start up, the hydrogen cooler with coated tubes performed 2°F cooler than the glass beaded bundle. The hydrogen coolers’s increased performance has remained constant throughout four months of peak operating temperatures and is now operating at 4°F cooler.

But only the right combination of components will provide effective and fail-safe hydrogen cooler ventilation. Just as a bowl will hold water when right side up, but will not when upside down, a hydrogen ventilation system will trap hydrogen unexpectedly if the geometry is arranged upside down or backwards.

Does that mean that the hotter stars have lots of hydrogen cooler stars very little? From the largest main condenser to the smallest hydrogen cooler, you can be assured our equipment will provide the results you demand. From the largest main condenser to the smallest hydrogen cooler, you can be assured our equipment will provide the results you demand.

Work on the turbine-generator project included replacement of the high-pressure turbine rotor, blade replacements for both low-pressure turbines, replacement of hydrogen cooler manufacturer, rewinding the main generator, and an overhaul of the exciter. Integral hydrogen coolers assembly for electric generators. They can tell you if you have a hydrogen cooler plugged or more likely valved out.

Extruded finned tube with or without liner tubes are available. The extruded finned tube is formed by a rolling process that raises fins in a continuous spiral on a straight length of tubing.

Random sample of bimetallic extruded finned tube is tested to ensure lower thermal contact resistance between fin and liner tube.

To properly support and convey the extruded finned tube, the machine has been equipped with quick-change steady-rest type roller conveyors. This movement enables the extruded finned tube to be withdrawn from the finning head and opens a passageway between the machine and the finned tube rack.

Extruded finned tubes are the general standard on the Enerfin heats exchanger for high temperature applications. Heat transfer surface typically consists of aluminum fins extruded over a liner tube, integral low finned tubing, or bare tube designs. Extruded fin tube offers excellent corrosion protection of the base tube. These forced oil / forced air coolers use special extruded finned tubes, utilizing optional metals, to provide one of the most efficient heat transfer surfaces available.

This fin is often referred to as a double-L fin and is often sold in place of extruded finned tubes. This extruded finned tube manufacturer is optimally shaped and has excellent thermodynamic properties.

The ambient air is cooled by humidification at the inlet of the extruded finned tube bundles. Enerfin-inc.com has developed the system which relies on the use of aluminum fintubes, and especially the famous bimetallic extruded finned tube.
Instead of winding a separate ribbon on to a bare tube, a form of extruded finned tube is available in which helical fins are extruded from the tube itself
by a rolling process.
Make sure that the bearing oil cooler is reconnected the right way around - the hose from the lower of the two fittings on the oil filter adapter on.

Enerfin designs and manufactures a complete line of custom bearing oil coolers. Using our extruded aluminium fin tubing, our coolers (type RHP) will give you the maximum surface required for your application.

We can offer various options to satisfy your request, ie; interior or exterior oil coolers with leak detector option.
Enerfin bearing oil coolers for motors and generators provide more cooling surface using fin tube construction.

In order to limit bearing oil cooler temperature to an acceptable value, auxiliary cooling means must sometimes be employed. The most common method is to insert a bearing oil cooler manufacturer into the thrust bearing oil cooler.
Improperly installing the torque converter can force the crank forward damaging the engine thrust bearing oil cooler.

Designs and manufactures immersion-style bearing oil cooler heat exchangers for industrial generators and motors. Many pumps have a bearing oil cooler available to provide the necessary cooling.

We also experimented with a vacuum cleaner in reverse to blow plenty of hot air through the gear box thrust bearing oil cooler to simulate desert conditions, but hot or cold air, the cooler hardly made any improvement.
A gear box manufacturer had told us before that we could expect trouble with a bearing oil cooler's operating completely submerged under oil.
Enerfin-inc.com sells air preheater. The air preheater is a static type with cast iron fin tube in the upper section and glass tube in the lower section.

A steam air heater is a simple radiator. The steam air heater consists of rows of finned tubes housed in an insulated metal case. The heat load is calculated from the quantity and specific heat of the air.

Hot oil liquid phase steam air heaters are used either alone, or when high inlet drying air temperatures are required, and the steam pressure is not high enough. The heater system consists of a stem air heater, which can be gas- or oil-fired, and an air heat exchanger.

The level of NOx in the process air after the direct fired natural gas steam air heater will depend on many variable factors, however, with a well adjusted air heater it should be limited to the above. Only about 2% of the NOx formed will be absorbed in the milk powder.

Steam Air Heaters are used for pre-heating air before it is introduced into the steam air preheater to avoid cold end corrosion. Steam Air Heater uses low-pressure steam, which is readily available in any process or power plant and brings up the temperature of the air from Amblent to around 60 °C.

The steam air heater, which exchanges heat from the exhaust gases to the incoming fresh air, is an important heat trap on most boilers. However, because it may operate close to the acid dew point of the exhaust flue gas and because there is usually a high pressure differential between the flue gas and the air sides, proper maintenance of the steam air heater is critical. Inspection of the steam air heater can only take place when the unit is out of service; therefore, it is important to quickly evaluate the maintenance requirements and carry out the necessary repairs. Our steam air heater manufacturers can help you make a prompt evaluation.

Steam air heaters or steam coils are heat exchangers in which one medium is steam being condensed while the other medium is a gas being heated when forced through the heat exchanger with a fan. Steam air heater can either have horizontal tubes or vertical tubes.

Enerfin extruded fin tubes are formed in a cold rotary extrusion process, where continuous helical fins tube are radially extruded from a thick aluminium muff over a liner fin tube. The process of extrusion hardens the fins and prevents dissimilar metal contacts at the fin root. Compared to other products, fins do not break, unwind or become loose which affects greatly thermal efficiency.

Enerfin can supply extruded fin tubes with or without liner in a variety of material. The extruded fin tube is formed from an outer aluminum tube with a large wall thickness (muff), which is aligned over an inner base tube.

To properly support and convey the extruded finned tube, the machine has been equipped with quick-change steady-rest type roller conveyors. The extruded fin tube is very robust and resistant to mechanical damage, allowing the fins to be easily cleaned with steam or water.

The extruded fin tube is formed from an outer aluminum tube with a large wall thickness, which is aligned over an inner base tube. This is an integrated and extruded fin tube which is fabricated by extruding fins from the aluminum bloom covered over the base tube.
The discharge from the generator cooler joins the outlet pipe extending from the fresh water cooler for overboard discharge. The pressure of the salt water before entering the fresh water generator cooler is indicated by a pressure gage and is controlled by a throttling valve located between the salt water pump discharge and the fresh water generator cooler. A similar valve is used to control the flow of water to the generator cooler.

This keeps the generator cooler, keeps down the noise, and keeps the interior of the generator cleaner. Would this not run the generator cooler and more efficient? The low temperature fresh water cooling system shall provide cooling of the diesel engine's low temperature stage of the charge air generator cooler, the lubricating oil cooler and if applicable the generator cooler.

Some of the waste heat from the engine, such as waste heat from hydro generator cooler manufacturer, can normally not be used for useful heat generation due to low temperature level.

The exhaust fan cooling system keeps the generator cooler for continuous operation. This generator cooler is ideal for holiday homes, caravans, camping and boating because of it's high performance and low maintenance, low vibration and low noise.

The engineers, who usually never open any generator, cooler, boiler or a turbine can now easily handle the critical tasks through their awakened drive. Discharge of uncontaminated storm water, intake screen backwash water, turbine oil cooler water, and hydrogen generator cooler water is permitted without limitations or monitoring requirements, except that there shall be no discharge of floating oil.
Enerfin Generator and Motor Cooler (RAM) are manufactured and designed to ASME codes and TEMA standards as required. Our motor coolers with removable covers can be manufactured using a variety of materials.

The Enerfin RAM type motor coolers are the new standard for quality using heavy-duty side casings, water boxes and extruded aluminium fin tubes. Compressor motor housing as an economizer and motor cooler in a refrigeration system. By removing the tape, we're able to keep the motor cooler manufacturer during a longer run.

The built-in cooling fin on the aluminum gearbox frame keeps the motor cooler. Cool suction gas keeps the motor cooler for longer life and better efficiency.
In addition, power consumption and wear on the entire drive train, motor cooler and holddown blowers have been substantially reduced.
A water distribution system provides a water supply to a gland and motor cooler. Helps keep motor cooler increases its longevity and efficiency.

Having an opening for the release of air, hood scoops with a front-facing opening feed the motor cooler air from outside the engine. The condition was caused by improper installation of a gasket on the inboard motor cooler which blocked all flow in that cooler and improper installation of a plenum in the other motor cooler which reduced flow through it by two-thirds.

The scrubber would be continuously flushed and cooled with condense water from the gas, pumped through an old car cooler placed in front of the regular motor cooler. A stainless steel cooling coil was cast within the component to keep the motor cooler and thereby run more efficient.
Cooling coil, along with the design decisions made to select them, can significantly impact the capital and life-cycle costs for thermal comfort. Regardless of the liquid medium used, the liquid is delivered to the cooling coil at a cold temperature. In the case of direct expansion equipment, the air passing over the indoor cooling coil heats the cold liquid refrigerant.

As this liquid passes through the indoor cooling coil on the inside of the heat exchanger, two things happen to the air that passes over the coil’s surface on the outside of the heat exchanger. Air flow over the indoor cooling coil also affects the coil’s capacity and is directly proportional to the total capacity of an AC system.

Two heat exchanger are placed in the air stream, one upstream of the cooling coil and the other downstream of the cooling coil. If we assume that a standard mixing box stratifies, or creates freezing air at the cooling coil at an outside air temperature of 26?F, the enhanced mixing box alternative could work with outside air in the 12? to 23? range. If enough heat is transferred, the outside air will be above freezing and the cooling coil is therefore protected.

Condensate removal by the cooling coil is greatly enhanced, often doubled by the heat pipes. The cooling coil is fabricated according to the customer's specifications with appropriate headers and fittings. The mixed air flows through the filters, through the cooling coil and into the heating coil.

The mixed air goes through the filters and into the cooling coil. The mixed air flows through the cooling coil where it gives up its heat into the chilled water tubes in the coil. Calculates central cooling coil loads for the months being considered in order to identify the maximum cooling coil load.
Enerfin transformer oil coolers (RHT) are custom designed to each customer's requirements and we have three main styles to suit most applications.

Enerfin OFAF (oil forced, air forced) transformer oil coolers are designed and manufactured using extruded aluminium fins. Transformer oil cooler comes complete with motor and fan assembly mounted and wired in a fan cabinet.

This will allow for normal plant operation even for the loss of a transformer cooler. In addition, operating under present conditions, a major reduction in generation capacity would have occurred for the loss of a transformer cooler during peak summer loads.

Similarly in transformer oil coolers are used to cool transformer oil by air or water. These transformer oil cooler play an important role in smooth functioning of main equipments. Our transformer oil coolers include different specifications and models such as integrated type, split type, suspended type and mobile type.

The configuration of a three-phase transformer cooler depends on the core type of the transformer used by the transformer oil cooler manufacturer. The radiators are connected to the transformer oil cooler by means of shut-valves. This method allows individual radiators to be removed without draining oil from the transformer.
The essential part of any substation transformer pump is the oil surrounding the core and coils. The heat caused by the core and coil losses affects the efficiency and life of the transformer pump.

One example occurred recently when a generator transformer pump at Koeberg experienced air ingress, leading to potential winding damage. Could I use this device to turn on both the transformer oil pump?

Transformers originally filled with conventional transformer oil pump can be retrofilled with a fire-resistant oil to increase the fire safety margin of these units. Transformers pumps that were designed for use with conventional transformer pump oil will run warmer when filled with a fire resistant oil.

Using a small transformer pump and hoses, manually flush the interior of the unit with warm retrofill fluid. Looking into the transformer pump suction inlet, the impeller must rotate clockwise or counterclockwise, as specified by the rotation arrow.

Make sure that the transformer pump cooling system has been flushed clean of dirt, and welding flash. The transformer pump itself would operate on perhaps 24 or 36 volts, supplied by a separate transformer outside the water.

The transformer pump units are generally designed for a specific application, and are therefore unique. A transformer pump is a device that uses waste heat to produce valuable heat on a higher temperature level than that of the waste heat.
