某厂一快装锅炉,型号为KZL416,经过2年的运行,出现煤燃烧不尽,灰渣中含碳量较高,出力不足的问题。分析原因为:1锅炉前拱部分塌落,导致不能将热量有效地反射给炉排上的煤,使煤不能及时预热燃烧,即煤的着火点靠后。2燃煤品种变换频繁,实际上是改变了锅炉原来的设计工况。鉴于
A factory a quick loading boiler, model KZL416, after 2 years of operation, there is an endless stream of coal combustion, high ash content of carbon content, lack of output problems. Analysis of the reasons: 1 part of the collapse of the front arch of the boiler, resulting in heat can not be effectively reflected to the grate on the coal, so that the coal can not be timely preheating combustion, that coal ignition point behind. 2 coal varieties change frequently, in fact, changed the original boiler design conditions. Given that
