FGR® recovers heat in the flue gas from solid fuel boilers.
A large part of the energy in the fuel is lost in the flue gases when burning biomass in a boiler. Relative to the gross calorific value, GCV, 25-40% of the energy is lost in a traditional boiler.
The FGR® can recover most of the heat and the latent heat of the vapor. The useful efficiency of a boiler system can be increased by 20%.
The FGR® also increases the total heat output of the heating system with 20-40%.
Fuel is saved in proportion to the efficiency increase. The FGR® will pay for it self, and after a few years the flue gas cleaning will be profitable.
