燃燒係統的維護痛點主要集中在“隻看火不看風”的盲目操作上。鍋爐要燒得好，燃料和空氣的配比必須精準。但很多司爐工隻憑經驗去調風門，導致爐膛內要麼空氣過剩，帶走大量熱量；要(yao)麼(me)配(pei)風(feng)不(bu)足(zu)，燃(ran)料(liao)燃(ran)燒(shao)不(bu)充(chong)分(fen)，冒(mao)黑(hei)煙(yan)。特(te)別(bie)是(shi)在(zai)燃(ran)油(you)燃(ran)氣(qi)鍋(guo)爐(lu)中(zhong)，燃(ran)燒(shao)器(qi)的(de)噴(pen)嘴(zui)和(he)點(dian)火(huo)電(dian)極(ji)如(ru)果(guo)積(ji)碳(tan)清(qing)理(li)不(bu)及(ji)時(shi)，就(jiu)會(hui)出(chu)現(xian)點(dian)火(huo)困(kun)難(nan)、打(da)火(huo)偏(pian)移(yi)甚(shen)至(zhi)爆(bao)燃(ran)的(de)危(wei)險(xian)。更(geng)有(you)甚(shen)者(zhe)，對(dui)爐(lu)膛(tang)內(nei)部(bu)的(de)耐(nai)火(huo)保(bao)溫(wen)材(cai)料(liao)掉(diao)落(luo)視(shi)而(er)不(bu)見(jian)，導(dao)致(zhi)爐(lu)體(ti)外(wai)表(biao)溫(wen)度(du)異(yi)常(chang)升(sheng)高(gao)，不(bu)僅(jin)熱(re)流(liu)失(shi)嚴(yan)重(zhong)，還(hai)容(rong)易(yi)燙(tang)傷(shang)巡(xun)檢(jian)人(ren)員(yuan)。
