    電采暖爐采暖過程中爐內變化有哪些?

    1、電采暖爐的爐內過程指燃料供應裝載將燃料供入爐,空氣直接或由送風機經空氣預熱器升溫后供入爐內,進行燃料的燃燒過程。媒在爐排或布風板上,經余熱干燥、干餾、揮發分逸出而著火燃燒,煤粉經煤粉燃燒器與空氣混合噴入,從而在爐膛空間燃燒,燃油經燃燒器霧化與空氣均勻混合在爐膛空間燃燒,燃氣經燃燒器與空氣均勻混合燃燒。燃燒產生的高溫煙氣對受熱面(水冷壁、過熱器、再熱器、凝渣管束、鍋爐管束、省煤器、空氣預熱器)內工質(水、汽、空氣)進行傳熱過程。然后,煙氣經除塵裝置除塵,經煙道、煙窗或加引風機排入大氣。生成的灰渣經除灰渣裝置排出爐外。
    1. The in furnace process of electric heating furnace refers to the process of fuel supply and loading to supply fuel into the furnace, and air is supplied into the furnace directly or after heating by forced draft fan through air preheater for fuel combustion. On the grate or air distribution plate, the medium is ignited and burned after waste heat drying, dry distillation and volatile escape. The pulverized coal is mixed and injected into the furnace space through the pulverized coal burner, so as to burn in the furnace space. The fuel oil is atomized and evenly mixed with the air through the burner, and the fuel gas is evenly mixed and burned with the air through the burner. The high-temperature flue gas generated by combustion transfers heat to the working medium (water, steam and air) in the heating surface (water wall, superheater, reheater, slag condensate tube bundle, boiler tube bundle, economizer and air preheater). Then, the flue gas is dedusted by the dust removal device and discharged into the atmosphere through the flue, smoke window or induced draft fan. The generated ash is discharged out of the furnace through the ash removal device.
    2、電采暖爐的鍋內過程指的是經過水處理的給水由給水箱加壓,經給水管道送入省煤器,經余熱升溫后近日上鍋筒,并沿下降管經下集箱流入輻射受熱面(水冷壁)和對流受熱面(凝渣管束、鍋爐管束)吸收煙氣熱量進行傳熱過程,生成高溫熱水,即熱水鍋爐?;蚴顾?,即是蒸汽鍋爐。
    2. The in pot process of electric heating furnace refers to the process that the water treated feed water is pressurized by the feed water tank, sent to the economizer through the feed water pipeline, heated by waste heat, then loaded into the boiler drum, and flows into the radiant heating surface (water wall) and convective heating surface (slag condensation tube bundle and boiler tube bundle) along the downcomer through the lower header to absorb flue gas heat for heat transfer, so as to generate high-temperature hot water, that is, hot water boiler. Or vaporize water, that is, steam boiler.
    高溫水或汽水混合物經集箱、引出管導入上鍋筒,完成了水循環。高溫水由上鍋筒或上集箱送往用戶,即熱水鍋爐。蒸汽鍋爐鍋筒內汽水混合物經汽水分離裝置提高干度后,蒸汽由鍋筒頂部送往用戶,或者送入過熱器,吸熱形成過熱蒸汽,從而送往用戶。
    The high-temperature water or steam water mixture is introduced into the upper drum through the header and outlet pipe to complete the water circulation. High temperature water is sent to the user by the upper drum or upper header, i.e. hot water boiler. After the dryness of the steam water mixture in the steam boiler drum is improved by the steam water separation device, the steam is sent to the user from the top of the drum or to the superheater to absorb heat to form superheated steam, which is sent to the user.
