煤在锅炉中的燃烧是一个复杂的化学反应过程,要完成燃烧全过程,除有足够的风量外,还必须有一定的炉膛容积和炉膛高度,对于链条炉,要有足够的炉排面积。总之,炉膛热强度和炉排热强度是炉子工作的重要指标,此外,对于合理布置和选择锅炉的炉膛拱形也非常重要。一炉膛拱形 1.前拱:快装水管式锅炉的前拱一般较短,对燃用挥发物少的煤种容易脱火,对劣质
Coal combustion in the boiler is a complex chemical reaction process, to complete the entire combustion process, in addition to adequate air volume, but also must have a certain furnace volume and hearth height, chain furnace, there should be sufficient grate area. In short, the furnace heat intensity and furnace heat intensity is an important indicator of the work of the furnace, in addition, for the rational layout and selection of boiler hearth shape is also very important. A furnace arch 1. The front arch: The front arch of the quick-loading water pipe boiler is generally short, easy to fire on coal with less volatile fuel, the poor quality
