焚烧炉常(chang)见故障及原因(yin)有(you)哪些?
焚烧炉在使用(yong)过(guo)程(cheng)中会出(chu)现一(yi)些常见的故障,下面(mian)新乡(xiang)双诚环保设(she)备网小(xiao)编(bian)就为大家分析一(yi)下出(chu)现这些故障的原因。
①火焰(yan)故障(zhang)报警
火焰故障如果(guo)发生在点火开(kai)始时和轻油(you)(you)燃烧阶段,可能是(shi)柴(chai)油(you)(you)柜油(you)(you)位(wei)过(guo)低(di),柴(chai)油(you)(you)中含有水分(fen),柴(chai)油(you)(you)系(xi)统阀门未正(zheng)常打开(kai),点火电极故障,轻油(you)(you)喷嘴异常,光敏电阻脏(zang)污,排烟挡板无法自动正(zheng)常动作(zuo)等等。
火焰故障(zhang)如果(guo)发生在污(wu)(wu)(wu)(wu)油(you)(you)(you)焚烧(shao)阶段,尤其是刚转(zhuan)(zhuan)7级时,多(duo)半是污(wu)(wu)(wu)(wu)油(you)(you)(you)中依(yi)然含有过(guo)多(duo)水(shui)份,当(dang)(dang)然也可(ke)能污(wu)(wu)(wu)(wu)油(you)(you)(you)质(zhi)量(liang)(liang)太差污(wu)(wu)(wu)(wu)油(you)(you)(you)火焰强度(du)(du)不(bu)足,可(ke)以(yi)适当(dang)(dang)调高(gao)(gao)污(wu)(wu)(wu)(wu)油(you)(you)(you)进计(ji)量(liang)(liang)泵(beng)(beng)压(ya)力(污(wu)(wu)(wu)(wu)油(you)(you)(you)柜圆柜1BAR)适当(dang)(dang)增加计(ji)量(liang)(liang)泵(beng)(beng)转(zhuan)(zhuan)速以(yi)增强污(wu)(wu)(wu)(wu)油(you)(you)(you)火焰强度(du)(du)。但是在我们的实践操作中,污(wu)(wu)(wu)(wu)油(you)(you)(you)燃烧(shao)是否(fou)顺利关键还是取决于(yu)污(wu)(wu)(wu)(wu)油(you)(you)(you)中所含水(shui)分多(duo)少,而(er)与(yu)污(wu)(wu)(wu)(wu)油(you)(you)(you)质(zhi)量(liang)(liang)影响不(bu)大(da)。污(wu)(wu)(wu)(wu)油(you)(you)(you)质(zhi)量(liang)(liang)好(hao),燃烧(shao)迅速,炉膛温(wen)(wen)度(du)(du)升高(gao)(gao)较(jiao)快,如果(guo)炉膛温(wen)(wen)度(du)(du)接近高(gao)(gao)温(wen)(wen)报警值,应该适当(dang)(dang)调低污(wu)(wu)(wu)(wu)油(you)(you)(you)进口压(ya)力和(he)计(ji)量(liang)(liang)泵(beng)(beng)转(zhuan)(zhuan)速。如果(guo)污(wu)(wu)(wu)(wu)油(you)(you)(you)质(zhi)量(liang)(liang)不(bu)好(hao),燃烧(shao)时炉膛温(wen)(wen)度(du)(du)持续下降,适当(dang)(dang)增加污(wu)(wu)(wu)(wu)油(you)(you)(you)压(ya)力和(he)计(ji)量(liang)(liang)泵(beng)(beng)转(zhuan)(zhuan)速,保持炉膛温(wen)(wen)度(du)(du)稳定在CCTSO以(yi)上。
②烟(yan)气温度高(375℃)或(huo)炉(lu)膛(tang)温度高(1200℃)报警(jing)而停(ting)炉(lu)。原因可能有四(si);⑴焚(fen)烧固体(ti)垃(la)圾(ji)时填充(chong)固体(ti)垃(la)圾(ji)太多。⑵焚(fen)烧污(wu)油(you)时污(wu)油(you)喷(pen)射量太大,适(shi)当降低污(wu)油(you)压力或(huo)计(ji)量泵(beng)转(zhuan)速。⑶炉(lu)膛(tang)进风(feng)量太小(xiao),进风(feng)风(feng)扇异常或(huo)进风(feng)口堵塞(sai)。⑷排(pai)烟(yan)挡板或(huo)排(pai)烟(yan)风(feng)机异常。
③污(wu)油喷嘴(zui)雾(wu)化不(bu)(bu)好,燃烧不(bu)(bu)好,炉膛内结碳严重,可能是(shi)污(wu)油喷嘴(zui)脏堵,污(wu)油压(ya)力过(guo)低或者雾(wu)化空气不(bu)(bu)足。
④燃(ran)烧室火(huo)焰不稳(wen)定,焚烧炉震(zhen)动大。可(ke)能原因是污油喷射(she)不稳(wen)定,排烟通(tong)道(dao)结(jie)碳脏堵,排烟风(feng)机或挡(dang)板(ban)异常,炉膛进风(feng)堵塞,风(feng)机叶片脏污轴承损坏等(deng)等(deng)。
