一、概述目前我国生产的快装链条炉排锅炉大部份都是为燃烧Ⅱ类,Ⅲ类烟煤设计的,煤质适应性差。由于我国幅员广阔,煤的储存、开采量虽大,但优质煤所占比例少。特别是近几年来,我国供应工业锅炉用煤多为挥发份很低的Ⅱ类无烟煤及煤质很差的Ⅰ类烟煤,很多用户只好以烧烟煤的锅炉燃烧无烟煤,以致造成锅炉出力不足(一般仅达到额 I. Overview At present, most of the quick-acting chain grate boilers produced in China are designed for the combustion of Class II and III bituminous coal, and the adaptability of coal is poor. Due to the vast territory of our country, the amount of coal stored and extracted is large, but the proportion of high-quality coal is small. Especially in recent years, most of the coal supplied to industrial boilers in our country is Class II anthracite with very low volatile content and Class I bituminous coal with poor coal quality, and many users have to burn anthracite coal with boilers burning bituminous coal, resulting in insufficient output of boilers Only reach the amount
