Abstract

The present invention relates to a method and system of recovering heat from flue gases generated in combustion devices (44) at a biomass-based plant, such as a pulp mill. The method to recover heat from flue gas including: directing flue gas from a combustion device through a flue gas cooler (52, 72); heating a circulation liquid in the flue gas cooler (52,57)with heat from the flue gas, and transporting the heated circulation liquid to a waste heat accumulator (50,70); flash cooling the heated circulation liquid in the waste heat accumulator; extracting from the waste heat accumulator flash vapor from the flashing of the heated circulation liquid; returning the flash- cooled circulation liquid from the waste heat accumulator (50,70) to the flue gas cooler (52,72), and controlling a flow of the circulation liquid through the flue gas cooler and waste heat accumulator based on at least one of a pressure and temperature of the circulation liquid.
