在钢铁企业中有大量的高炉煤气、焦炉煤气、转炉煤气等可燃副产品．用这种燃料的锅炉，其热力试验和热力计算有若干特点，如高含氮量的气体燃料过量空气系数的算法，气体燃料特性系数出现负值，将给定燃料的热量份额换算成体积份额，试验中多个取样断面等．文中结合上海宝山钢铁集团公司工业锅炉的燃烧调整试验加以分析，对数量众多的燃烧冶金煤气锅炉的试验或计算是有参考意义的
In the iron and steel enterprises have a large number of blast furnace gas, coke oven gas, converter gas and other combustible by-products. There are several characteristics of the thermal test and thermodynamic calculation of a boiler using such a fuel, such as an algorithm of excess air coefficient of gaseous fuel with high nitrogen content, a negative value of the characteristic coefficient of gaseous fuel, conversion of the heat content of a given fuel into a volume fraction , Test multiple sampling cross-section and so on. In this paper, with the analysis of combustion adjustment test of industrial boiler in Shanghai Baoshan Iron and Steel Group Corporation, it is of great significance for the test or calculation of a large number of combustion metallurgical gas boilers
