Raising thermal efficiency with condensation heat exchangers

At especially low return temperatures (below ca. 50 °C) it is often sensible and profitable to gain additional heat from the exhaust. The additional heat can increase the CHP unit’s regular thermal power by up to ca. 15 % (without any additional gas consumption) and therefore raise the unit’s total efficiency by several percentage points.

To do so, a condensation heat exchanger is installed in the return flow to the CHP unit. This heat exchanger cools the exhausts below the dewpoint and transfers the gained condensation heat to the heating water. Besides the return flow temperature the space requirement (ca. 4 m length) and the exhaust backpressure must be considered.

Our sales engineers will be happy to help you check if the use of a condensation heat exchanger is sensible in your CHP project.
