    • A compact fire tube boiler (200) comprises: a first heat transfer zone (202) having a furnace (212) which receives flue gases having a pressure between 500-2000 mmWC and combusts a fuel therein, to generate flue gas at a temperature between 1300-1400 °C, wherein, in the first heat transfer zone (202), 30-35% of heat is extracted; a second heat transfer zone (206) having convective tubes (222) principally adapted to transfer the hot flue gases from the first heat transfer zone (202) to a third heat transfer zone (204) while extracting only 10-15% of heat therefrom; and the third heat transfer zone (204) which is the main convective pass having convective tubes (224), extracts 55-60% of heat therein. The compact fire boiler (200) reduces power consumption by 60-80% and footprint by 30%.
    • 小型消防管式锅炉(200)包括:具有炉子(212)的第一传热区域(202),其接收压力在500-2000mmWC之间的烟道气并在其中燃烧燃料,以产生烟道气, 1300-1400℃,其中,在第一传热区(202)中,提取出30〜35%的热量; 第二传热区(206),其具有主要适于将热烟道气从第一传热区(202)转移到第三传热区(204)的对流管(222),同时仅从其提取10-15%的热量 ; 并且作为具有对流管(224)的主对流通道的第三传热区(204)在其中提取出55-60%的热量。 紧凑型消防锅炉(200)将功耗降低了60-80%,占地面积减少了30%。
