Exhaust-water preheater for biomass cogeneration plant

 Old and residual wood is burned in a biomass cogeneration plant. The combustion takes place in a stationary fluidised bed boiler. Due to the intended use of the energy of the exhaust gas flow after the filter, an additional exhaust gas heat exchanger should be installed as heat recovery. On the water side, the exhaust gas heat exchanger should be operated with district heating water.

For this case of need we supplied a finned tube heat exchanger and newly designed exhaust gas ducts, as well as a corresponding galvanized steel construction to accommodate the heat exchanger. In a planned 2-week plant shutdown, the components were delivered and assembled by us by truck.

Heat recovery capacity through the new finned tube heat exchanger: approx. 1.0 MW/h
