1、DZL系列臥式快裝鍋爐產(chǎn)品介紹DZL系列單鍋筒臥式快裝鏈條爐排燃煤水管鍋爐,設計燃用煙煤或無煙煤。鍋爐蒸發(fā)量2?8t/h,工作壓力0.7?2.5Mpa,飽和蒸汽或過熱蒸汽。熱水鍋爐容量為2.8?5.6MW,出水溫度95°C、115°C.130°C,冋水溫度為70°C,工作壓力為0.7?1.6Mpao本系列鍋爐為部優(yōu)節(jié)能產(chǎn)品,結(jié)構(gòu)緊湊,外形尺寸小,單層布置,安裝周期短,基建投資少等優(yōu)點。鍋爐爐膛左右側(cè)裝有光管水冷壁管,上連鍋筒,下連兩側(cè)集箱和前后墻組成燃燒室,在鍋筒內(nèi)部置兩束煙管,在爐膛燃燒后的煙氣在煙管內(nèi)作兩個回程縱向沖刷后,引至尾部單-獨布置的鑄鐵省
2、煤器,最后經(jīng)除塵器排入煙囪。鍋爐下部為燃燒設備,采用輕型鏈條爐排,本鍋爐配冇上煤機、出渣機、電控箱,可實現(xiàn)上煤出渣機械化及給水口動控制。DZL新型水火管鍋爐是我公司引進北京之光鍋爐研究所開發(fā)的新一代高效節(jié)能鍋爐產(chǎn)甜之一。鍋爐蒸發(fā)量1?20t/h,工作壓力0.7?1.6Mpa,飽和蒸汽或過熱蒸汽。熱水鍋爐容量為0.7?14MW,出水溫度95°C、115°C.130°C,冋水溫度為70°C,工作壓力為0.7?1.6Mpao它結(jié)構(gòu)緊湊,外形尺寸小,單層布置,安裝周期短,基建投資少。鍋爐設計燃用煙煤或無煙煤,燃料口分層煤斗落到爐排上,進入爐膛燃燒,燃燒產(chǎn)物自爐
3、膛經(jīng)隔墻煙氣出口窗進入翼形煙道,從后向前沖刷管朿后進入第二鍋爐管束,煙氣由前而后沖刷螺紋煙管后進入除塵器、引風機至煙囪排入大氣。本鍋爐采用自然循環(huán)方式,合理布置毎片管束,采用回水引射,這樣就形成了良好的水循環(huán),從而保證了回水的良好吸熱及鍋爐的安全性。IntroductiontoDZLSeriesHorizontalPackageBoilerBituminouscoaloranthracitecoalisdesignedforDZLseriessingle-barrelhorizontalpackagechaingratecoalburningwater
