Abstract

Patente de Invenção: <B>"OPERAçãO DE SISTEMA GERADOR DE VAPOR''<D>. A temperatura de gás de combustão (22) proveniente de um preaquecedor de ar (14) para um dispositivo coletor de particulado tal como um precipitador eletrostático (16) ou filtro de tela é reduzida para aperfeiçoar a operação do dispositivo coletor de particulado. Isto pode ser realizado pelo reduzir a temperatura do gás de combustão de saída (22) do preaquecedor de gás (14) ou reduzir a temperatura após a saída. Em uma concretização, o ar em excesso daquele necessário para combustão é passado através do preaquecedor de ar (14) com o ar excedente aquecido quer sendo descarregado (34) quer usado para uma variedade de finalidades (30,32) na planta. Uma concretização específica envolve segmentar o lado de saída de ar de um preaquecedor de ar regenerativo rotativo (14) e extrair o ar excedente do segmento onde a carga de poeira é mais baixa. Outrossim, resfriamento adicional do gás de combustão (22) pode ser previsto pelo reduzir a quantidade de ar primário que tipicamente ultrapassa o preaquecedor de ar (14) e a seguir proporcionando outras maneiras para controlar a temperatura do ar primário para os pulverizadores. A temperatura do gás de combustão (22) também pode ser resfriada após o preaquecedor de ar (14) por trocador de calor ou resfriamento por pulverização com água.
