Abstract

sistema e método para recuperação de calor de gases de combustão. a presente invenção refere-se a um método e a um sistema de recuperação de calor a partir de gases de combustão gerados em dispositivos de combustão em uma usina à base de biomassa, tal como uma fábrica de celulose. o método para recuperar calor a partir do gás de combustão inclui: direcionar o gás de combustão a partir de um dispositivo de combustão através de um resfriador de gás de combustão; aquecer um líquido de circulação no resfriador de gás de combustão com o calor proveniente do gás de combustão, e transportar o líquido de circulação aquecido até um acumulador de calor residual; resfriar instantaneamente o líquido de circulação aquecido no acumulador de calor residual; extrair a partir do acumulador de calor residual o vapor instantâneo proveniente da vaporização instantânea do líquido de circulação aquecido; retornar o líquido de circulação resfriado instantaneamente a partir do acumulador de calor residual até o resfriador de gás de combustão e do acumulador de calor residual com base em pelo menos uma pressão ou em uma temperatura do líquido de circulação.system and method for combustion gas heat recovery. The present invention relates to a method and system of heat recovery from flue gases generated in combustion devices in a biomass-based mill, such as a pulp mill. The method for recovering heat from flue gas includes: directing flue gas from a combustion device through a flue gas cooler; heating a circulating liquid in the flue gas cooler with heat from the flue gas, and transporting the heated circulating liquid to a waste heat accumulator; instantly cool the heated circulation liquid in the waste heat accumulator; extracting instantaneous vapor from the waste heat accumulator from instantaneous vaporization of the heated circulating liquid; Return the cooled circulating liquid instantaneously from the waste heat accumulator to the flue gas cooler and the waste heat accumulator based on at least one pressure or temperature of the circulating liquid.
