燃烧室结渣
slagging in furnace

过粗等;④嫩烧设备存在严重缺陷,如嫩烧器喷嘴烧损,炉膛水冷壁管翘曲变形,严重漏风等;⑤缺少足够的吹灰手段,吹灰器数量不足,安装不良或损坏;⑥锅炉负荷过高或给水温度太低(远低于设计值)等。 防止结渣的措施新设计的锅炉,主要是对设计煤种的结渣沾污特性预先做出判断,用以确定炉膛热负荷强度等设计参数。目前,可用一种将若干单项结渣指标(如飞灰烧结强度、基于煤灰熔融特性、灰成分及猫度特性等的结渣判据)通过模糊数学处理方法予以综合得出判定结论;也可以采用试验台实测法确定煤粉嫌烧结渣倾向等级.对已投人运行的锅炉,则应进行具体分析,找出主要影响因素,分别采取针对性措施予以消除。根据经验,可采取的措施主要有:①进行必要的嫩烧工况优化调整,消除引起严重结渣的不合理运行工况因家,包括调整燃烧器配风方式,维持最佳的过t空气系数及煤粉细度,防止火焰偏斜和冲刷炉壁等;②进行全面的燃料特性分析,特别是灰的成分分析及灰熔点和结渣特性测定;必要时进行混煤配比试验,寻求提高灰熔点的配比;③当确认由于燃烧设备设计不良所致时,进行适当的技术改造,例如采用偏置二次风嫌烧器,调整直流嫌烧器喷口间距,更换新型旋流燃烧器,或避免嫩烧过分集中,减小燃烧器区域壁面热强度等等;④对于燃用低挥发分煤种的锅炉,炉膛水冷壁敷有耐火涂料的燃烧带时,可适当拆除部分或全部卫燃带,⑤配t足够数量运行效果良好的吹灰器,及时吹灰,切勿等到积灰严重时再吹,否则吹灰效果将会大大下降;⑥彻底消除燃烧设备缺陷,认真消除炉膛及制粉系统漏风,⑦作为临时性措施,可适当降低负荷或周期性地减负荷运行。 近年来有使用除渣剂添加在燃煤中,使结渣松软而易于清理,但已显露出有腐蚀受热面的问题,要慎重使用。ronshooshl Jlezha在锅燃烧室结渣(slagging in furnace)乙半熔炉妒脸内进行的燃烧过程中受热面上猫结软化亘现象。融灰粒,并生长和积累形成硬结的渣体覆盖层的二域和嫩煤炉中发生结渣的部位,通常在燃烧器布置〔冬后的炉膛出口折焰角处,严重时还会在过热器屏及;对流管束人口等处发生,也有时在炉膛下部冷灰斗夕结渣或堆渣。炉膛结渣致使炉膛辐射吸热量下降,炉「烟温水平上升,反过来更促使结渣过程加速发展,同日引起后部受热面上积灰加剧。在炉内和嫌烧器区域尹重结渣,会影响炉内良好的空气动力工况,使燃烧进-步恶化。局部地区堵渣或堵灰也会形成烟气走廊,导互局部受热面严重磨损或过热。由于以上种种因素,最乡会导致降低负荷运行或被迫停炉。炉膛上部水冷壁_结成的大渣块往往会脱落下来,砸坏炉底管。
