Flue Gas Heat Recovery systems (FGHRS): Data requirements

Flue gas heat recovery systems (FGHRS) are designed to recover heat in the flue gases discharged from a boiler. They use the cold temperature of the domestic cold water supply to recover extra heat that is not extracted by the boiler. The amount of heat that can be extracted by a boiler is usually limited by the

The heat is transferred directly from the hot flue gas to a steam boiler or circulating thermal oil system. The quantity of flue gas and the associated exit gas temperature limit the amount of heat recovered. These systems can typically recover up to 70-80% of the theoretical heat available in the flue gas.

WASTE HEAT RECOVERY TECHNOLOGIES FROM HEATING

Recovery of heat contained in the flue gas leads to the increase of thermal efficiency and thus to the decrease of boiler fuel consumption and pollutant emissions. To recover as much as possible of the waste heat, exhaust gas must be cooled deeper to recover both sensible heat of the flue gas and latent heat of water vapour from flue gas.
