工业妒、窑是我国的用煤大户.据统计,每年将消耗原煤四亿多吨,接近年总采煤量的40%.由于这些炉、窑的燃烧效率、热利用率很低,所以已成为我国平均单位能耗高的主要因素.提高这些数量众多的工业炉、窑热利用效率,是降低我国能耗的主途径之 According to the statistics, more than 400 million tons of raw coal will be consumed each year, which is close to 40% of the total amount of coal mined in the year. Because of the low combustion efficiency and low heat utilization rate of these furnaces and kilns, industrial kilns are the major coal- Become China’s average unit of high energy consumption of the main factors to improve these large number of industrial furnace kiln utilization efficiency is to reduce the main way of energy consumption in China
