This exchanger, based on a Pillow Plate coil, is a derivation of the Process-Therm, but can be even larger in size and heat exchanged.

Flue gas condensers are used in combustion plants using ‘wet’ fuels, such as biomass or household waste.

The flue gas from the burner, after releasing energy at high temperature in the boiler, circulates around the outside of the condenser plates, while inside there is a circulation of water, which may be, for example, water from district heating networks, or water used to heat industrial processes.  The moisture contained in the combustion gases condenses, allowing latent heat to be recovered. Depending on the size of the plates, very low gas/liquid DTs can be obtained, and the efficiency of these exchangers can be maximised.

This type of condenser has proven operational experience in thermal power generation or cogeneration plants (with boilers from 2 to 250MW).
