Abstract

"MéTODO EM UMA CALDEIRA DE RECUPERAçãO DE SODA, E, CALDEIRA DE RECUPERAçãO DE SODA". Em uma caldeira de recuperação de soda, os gases de combustão são orientados através do denominado economizador (3) para recuperar calor dos gases de combustão. Os gases de combustão são" resfriados no último estágio do economizador (3) com o resfriador água de circulação (4) para os gases de combustão, separado do sistema de alimentação de água de caldeira. O resfriador de água de circulação (4) para os gases de combustão é utilizado para pré-aquecer o ar de combustão.
