Abstract

resumo "alimentador de combustível de fase dupla para boilers" a presente invenção se refere um alimentador de combustível de fase dupla que pode ser usado para fornecer tanto combustíveis sólidos quanto combustíveis líquidos para um boiler, tal como um boiler de leito fluidizado. o alimentador de combustível inclui uma rampa inclinada que define um caminho de alimentação sólida. os bocais de distribuição de gás são situados na base do alimentador de combustível, e os bocais secundários são situados de modo a serem capazes de distribuir um combustível líquido ou particulado para o caminho de alimentação só-lida. isso permite que o combustível líquido contate o combustível sólido e seja transportado para o leito fluidizado em vez de se tornar suspenso acima do leito.
