Exhaust gas heat exchangers in CHP

As a leading business for exhaust gas heat exchangers, we look back at thousands of successful projects. An exhaust gas heat exchanger uses the waste heat from combined heat and power units (CHP), usually to generate hot water or to heat thermal oil.

Typical fuel gases or liquid fuels for engines include natural gas, biogas, sewage gas, other special gases, diesel or vegetable oils. The choice of materials for exhaust gas channels, tubes and tube sheets depends on the fuel used and the application. All equipment is tested and certified in accordance with the European Pressure Equipment Directive. Other certification like ASME or the EAC (Eurasian Economic Union) is available upon request.

Additional equipment for exhaust gas heat exchangers includes exhaust gas bypass systems, insulation, heat recovery units with engine waste heat recovery and safety devices as required. For highly polluting or sooty exhaust gases, clean-in process systems from APROVIS improve the performance of the exhaust gas heat exchanger and can also reduce the amount of servicing they require, thereby lowering costs.
