以国产35t/h大型链条炉为例,防焦箱是一重要受压部件,也是经济燃烧不可缺少的设备。它布置在炉排的两侧,为防止煤层在强烈燃烧时,在两侧墙下部结焦块而设置的。1问题的提出防焦箱目前有两大问题,一直在威胁着锅炉的安全经济运行。1)每侧防焦箱由2节组成,中部相邻的2个无孔封头出现裂纹,当泄漏时就必须停炉,而且修复比较困难。2)防焦箱迎火面下角的密封铁,经常烧坏,形成边排漏风、影响经济燃烧。
To domestic 35t / h large chain furnace, for example, anti-Jiao Xiang is an important pressure components, but also an indispensable economic combustion equipment. It is arranged in the grate on both sides, in order to prevent the coal in the intense combustion, the two sides of the wall coking blocks set. A problem put forward Coke prevention box currently has two major issues, has been threatening the safe and economical operation of the boiler. 1) Each side of the coke prevention box consists of 2 sections, two adjacent non-porous head cracks in the middle, when the leak must be shut down, and the repair is more difficult. 2) anti-coke fire box bottom corner of the sealed iron, often burn, the formation of side discharge air leakage, affecting economic combustion.
