工业锅炉每年约消耗二亿吨原煤,占整个国家能源消耗的1/3。随着我国轻重工业的发展,工业锅炉的数量大量增加.据1979年的初步统计,我国目前正在使用的工业锅炉约18万台,其中包括热水锅炉3万台。这些锅炉的热效率大多设计在60—80％,考虑到煤种,运行后的积灰结垢及运行保养水平,实际使用的锅炉热效率往往低于此数. 很多单位由于生产的发展,供气量增加,但国内工业锅炉供应不足, Industrial boilers consume about 200 million tons of raw coal each year, accounting for 1/3 of the country’s energy consumption. With the development of light and heavy industries in our country, the number of industrial boilers has increased substantially, and according to preliminary statistics in 1979, there were about 180,000 industrial boilers currently in use in our country, including 30,000 hot water boilers. Most of the thermal efficiency of these boilers is designed at 60-80%, taking into account coal, fouling after the operation and maintenance level, the actual use of the boiler thermal efficiency is often lower than this number of units due to the development of production, gas supply Increase, but insufficient supply of domestic industrial boilers,
