技术介绍
燃煤和燃油锅炉在运行过程中,尾部受热面普遍产生积灰,使烟气阻力增加,排烟温度升高,严重影响锅炉的正常运行。国内外常用的蒸汽吹灰技术在很多情况下不适于清除锅炉尾部积灰,除灰效果很不理想,主要原因是蒸汽吹灰会导致烟气湿度增加,更容易造成积灰和堵塞,有时还会使腐蚀加剧,对含钙量或含硫量较高的灰更是如此。燃气脉冲吹灰器是一种性能先进的新一代除灰设备,燃气脉冲吹灰器利用乙炔或煤气、天然气、液化石油气等常用气体燃料,在特殊设计的燃烧室中燃烧,并以输出管上的喷口处发射出冲击波,通过冲击波的作用使受热面上的积灰脱落,除灰效果显著。然而,对于垃圾炉、冶金培烧炉、生物质炉、玻璃及水泥行业余热炉等锅炉,由于锅炉内产生的烟气腐蚀性极强,会对燃气脉冲吹灰器内的喷管和脉冲发生器罐体内侧产生严重的腐蚀。这种腐蚀现象发生的原因在于燃气脉冲吹灰器是一种间歇性工作的设备,当系统运行时,喷管及脉冲发生器罐体内的压力大于烟道内压力,而当燃气脉冲吹灰系统停止工作时,喷管及脉冲发生器罐体内压力骤减,相较于烟道的正压消失,烟道内的 ...
