工业锅炉是一种数量多、分布面广、能耗大的热力设备。据有关部门统计,1983年全国工业锅炉已达到二十七万三千余台,四十多万蒸吨,这些锅炉平均热效率约55％,每年耗煤二亿吨。如果能把工业锅炉效率提高到约70％,那么每年就可节煤数千万吨,可见工业锅炉的节能的确是大有可为的。在我国,所谓工业锅炉是指各种压力下工作的额定蒸发量小于65吨/时的锅炉;工作压力小于25公斤力/厘米~2的各种容量的锅炉及特别用途的锅炉,其中也包括不同容量的热水锅
Industrial boiler is a large number of large-scale distribution, large energy consumption of thermal equipment. According to statistics from relevant departments, in 1983, the number of industrial boilers in the country reached over 273,000 and more than 400,000 tons of steam. The average thermal efficiency of these boilers was about 55% and coal consumption was 200 million tons per year. If you can increase the efficiency of industrial boilers to about 70%, then every year can save tens of millions of tons of coal, showing that energy-saving industrial boilers is indeed promising. In our country, the so-called industrial boilers refer to boilers with rated evaporation less than 65 tons / hour under various pressures, boilers of various capacities and working pressure less than 25 kgf / cm2, and boilers of special purpose, including Different capacity hot water pot
