燃氣鍋爐燃燒(shao)器(qi)構造由以下5個(ge)系(xi)統組成(cheng):
1、送風(feng)(feng)系(xi)統。送風(feng)(feng)系(xi)統的(de)功能(neng)在于向燃燒室里送入一定風(feng)(feng)速和風(feng)(feng)量的(de)空(kong)氣(qi),其主要部件有:殼(ke)體、風(feng)(feng)機(ji)馬達、風(feng)(feng)機(ji)葉輪(lun)、風(feng)(feng)槍火管(guan)、風(feng)(feng)門(men)(men)控制(zhi)器、風(feng)(feng)門(men)(men)檔(dang)板、凸輪(lun)調節機(ji)構、擴散(san)盤。
2、點(dian)火(huo)系(xi)統(tong)。點(dian)火(huo)系(xi)統(tong)的功能在于點(dian)燃(ran)空氣與(yu)燃(ran)料的混(hun)合物(wu),其(qi)主要部件有:點(dian)火(huo)變(bian)壓(ya)器、點(dian)火(huo)電(dian)極、電(dian)火(huo)高壓(ya)電(dian)纜。較為安(an)(an)(an)全(quan)的一(yi)種點(dian)火(huo)系(xi)統(tong)稱為電(dian)子脈(mo)沖點(dian)火(huo)器,被卓益節能等燃(ran)氣鍋爐廠家(jia)所(suo)廣泛使用。其(qi)方(fang)便省(sheng)時,只需用手指按動就(jiu)可以,并(bing)且安(an)(an)(an)全(quan)性高,不會(hui)出現因意(yi)外熄火(huo)出現的安(an)(an)(an)全(quan)事(shi)故(gu),一(yi)旦(dan)出現熄火(huo)的狀(zhuang)態,控(kong)制系(xi)統(tong)能及時關閉電(dian)磁閥,關斷燃(ran)氣通(tong)路。
3、監(jian)測(ce)系統。的功(gong)能在(zai)于保(bao)證燃燒器(qi)(qi)安(an)全、穩定的運行,其主要部(bu)件有火焰監(jian)測(ce)器(qi)(qi)、壓力監(jian)測(ce)器(qi)(qi)、溫度監(jian)測(ce)器(qi)(qi)等。
4、燃(ran)(ran)料系(xi)(xi)統(tong)。燃(ran)(ran)料系(xi)(xi)統(tong)的(de)功能在于保證燃(ran)(ran)燒(shao)(shao)器燃(ran)(ran)燒(shao)(shao)所需的(de)燃(ran)(ran)料。燃(ran)(ran)油燃(ran)(ran)燒(shao)(shao)器的(de)燃(ran)(ran)料系(xi)(xi)統(tong)主要有:油管及接頭(tou)、油泵、電(dian)(dian)磁(ci)(ci)閥、噴嘴、重油預(yu)熱器。燃(ran)(ran)氣燃(ran)(ran)燒(shao)(shao)器主要有過濾器、調壓器、電(dian)(dian)磁(ci)(ci)閥組、點(dian)火(huo)電(dian)(dian)磁(ci)(ci)閥組然、燃(ran)(ran)料蝶閥。
5、電控(kong)(kong)系(xi)(xi)統。電控(kong)(kong)系(xi)(xi)統是以(yi)上各系(xi)(xi)統的指揮中(zhong)心和(he)聯絡(luo)中(zhong)心,主要控(kong)(kong)制元件為程控(kong)(kong)器,針對不同(tong)(tong)的燃燒器配有不同(tong)(tong)的程控(kong)(kong)器,常見的程控(kong)(kong)器有:LFL系(xi)(xi)列(lie)、LAL系(xi)(xi)列(lie)、LOA系(xi)(xi)列(lie)、LGB系(xi)(xi)列(lie),其(qi)主要區別(bie)為各個程序步驟(zou)的時間不同(tong)(tong)。
