我厂原有老式K_2锅炉两台,长期存在着耗煤量大,热效率低,经测得每吨蒸汽耗煤量为305公斤,最大蒸发量为1.48吨/时,而且操作条件差,烟尘严重,黑烟滚滚,污染环境。为此我厂改造了这两台老式K_2锅炉,对改造后的两台新锅炉进行技术测定表明:蒸发量提高到4吨/时,每吨蒸汽耗煤量降到168公斤(蒸发量是在新炉而又间断运行情况下测定的);比改造前 I plant the original two old K_2 boilers, long-term existence of large coal consumption, low thermal efficiency, the measured coal consumption per ton of steam was 305 kg, the maximum evaporation of 1.48 tons / hour, and the poor operating conditions, serious smoke Smoky, pollute the environment. To this end, our factory rebuilt these two old-style K_2 boilers and conducted technical tests on the two new boilers after the retrofit. The results show that when the evaporation is increased to 4 tons / hour, the coal consumption per tonne of steam is reduced to 168 kilograms Furnace and intermittent operation under the determination of); than before the transformation
