Engines for combined heat and power plants are operated with different fuels, including hydrogen, natural gas, biogas, sewage gas and special gases, plus diesel and other liquid fuels. In an exhaust gas heat exchanger, the hot exhaust gas from the CHP engines or CHP gas turbines is cooled, in the process heating water, a water-glycol mixture or thermal oil. This thermal energy can be used in a local or district heating system or for other industrial purposes.

Exhaust gas bypass systems are made as additional equipment in exhaust gas heat exchangers. 3-way flap is required for bypass systems. By-passing the gas flow makes it possible to adjust temperature inside boiler (exhaust gas heat exchanger). Before delivery, we do a thorough test drive for every single damper, using actuator and special measurement equipment, to make sure that they function as expected and are ready to serve reliably on site. Availaible in steel, stainless steel or heat resistant materials Flange type and size depending on customer needs We develop dampers in different sizes and various temperature ranges Actuator options; Pneumatic actuator, Electrical actuator

Heat transfer between a gaseous media and a liquid finned tube heat exchangers are often called air/water heat exchangers or gas/water heat exchangers. Heat transfer between a gas (for ex. air, steam) and a liquid (for ex. water, seawater, oil) takes place in the air-/water heat exchangers. Very often air/water heat exchangers are used as exhaust heat exchanger to gain the energy out of warm or hot exhaust fumes. Finned tube radiators can also be used as air heater, air cooler or condenser To improve the thermal output transfer from the gas to the liquid, fins made of well heat transferring materials are put on the tubes. The great increase of the thermal efficiency when applying fin tubes allows a substantial reduction in size and costs of such cooling equipment. The surface of such tubes is substantially increased and consequently less tubes are required compared with exchangers with plain tubes.

Air-water / air-air heat exchanger as smooth tube heat exchanger up to 1,000 ° C Smooth tube heat exchanger as an air / water heat exchanger In the case of air-water heat exchangers (also called gas-water heat exchangers), a temperature exchange takes place between a gas (usually air) and a liquid. As a rule, the liquid medium flows inside the pipes, while the gaseous medium flows around the pipes outside the pipes. Smooth tube heat exchangers can cover various areas of application: heating, cooling and condensing as well as heat recovery. Smooth tube heat exchanger as air-to-air heat exchanger Smooth tube heat exchangers are also often used as air-to-air heat exchangers. In this application, a gas (e.g. exhaust air or exhaust gases) flows inside the pipes and a gas (e.g. fresh air) outside the pipes around the pipes.

Temperature control of gaseous and liquid media Flat tube heat exchangers are generally used as air / air or air / liquid heat exchangers. Flat tube heat exchangers are used where the (exhaust) air is polluted and the installation space is limited. In heat recovery in particular, there are numerous applications for flat tube heat exchangers as so-called exhaust gas / exhaust air heat exchangers. Little installation space and less pressure loss While the rows of tubes in smooth tube heat exchangers consist of round tubes, the rows of tubes in flat tube heat exchangers have a special profile (see illustration). This special tube profile offers advantages over the round profile in certain applications. Flat tube heat exchangers require less installation space than smooth tube heat exchangers with the same exchange area and are therefore also lighter.

Temperature exchange between a gas and a liquid In the case of air-water heat exchangers (also called gas-water heat exchangers), there is a temperature exchange between a gas (usually air) and a liquid. Finned heat exchangers can cover various areas of application: - heating and evaporating, - cooling and condensing as well as heat recovery. In this context, lamellar heat exchangers are also called air heaters or air coolers. Air-water heat exchangers are often also used as exhaust gas heat exchangers or flue gas heat exchangers in order to recover the energy from warm or hot exhaust gases. Lamella packs for a large exchange area In order to achieve the largest possible exchange surface between the air and the medium (liquid) within the heat exchanger, lamellas or lamella packs are attached to the pipe system.

Air heat exchangers as finned tube heat exchangers Heat transfer between a gaseous media and a liquid Finned tube heat exchangers are often called air/water heat exchangers or gas/water heat exchangers. Heat transfer between a gas (for ex. air) and a liquid (for ex. water) takes place in the air-/water heat exchangers. To improve the thermal output transfer from the gas to the liquid, fins made of well heat transferring materials are put on the tubes. Very often air-/water heat exchangers are used as exhaust heat exchanger to gain the energy out of warm or hot exhaust fumes. Finned tube heat exchangers can also be used as air heater, air cooler or condenser.

  THERMO-GAS Heat Exchangers work optimally if the constant flow of gasses into the heat exchanger is guaranteed. In case of unfavourable assembly conditions, we have made tests and measurements  so far in order to optimise stream conditions. Due to the increased requirements  on the performance of heat exchangers as well as expanded application areas it has become necessary to achieve optimised results already in the planning phase. This is done by means of a CAD-based simulation which enables the very exact predicition of stream conditions. The performance opportunities of our heat exchangers are used at the best as a result of appropriate installed equipement for flow duct. We would be pleased to provide you with our knowledge also beyond the heat exchanger technology.     The precise project   In case of a plant for catalytic combustion, the connecting hood to the heat exchanger was  significantly shortened due to the assembly of a THERMO-AWT 3-Way Stop valve. After this

Closed circulation vacuum system is consisted with liquid ring vacuum pump and compressor, liquid and gas separator tank, heat exchanger, instrument and valves, internal pipeline, and common base plate. The pumped gas enters the liquid ring vacuum pump/compressor from the pump inlet, after compressed by the liquid ring vacuum pump/compressor, the gas will enter to enter the gas-liquid separator together some of the working liquid. Inside the gas-liquid separator, the gas and liquid are separated, and the gas is discharged from the pump outlet, and the working fluid go from the heat exchanger and enter the liquid ring vacuum pump/compressor for recycling.
