生物質熱風爐要及時清除熱風爐受熱面的積灰

 

要及時清除受熱面積灰.采用最適合生物質燃料燃燒燃燒設備----往復爐排。在結構設計上,相對傳統爐膛空間較大,同時布置非︰俠磯畏,有利于生物質燃料燃燒時瞬間析出大量揮發分充分燃燒。

Biomass hot-blast stove should remove ash on heating surface of hot-blast stove in time. Hot-blast stove adopts reciprocating grate, which is the most suitable combustion equipment for biomass fuel combustion. In the structure design of hot blast stove, compared with the traditional hot blast stove, the furnace has larger space and reasonable secondary air arrangement, which is conducive to the full combustion of a large amount of volatile matter released in the instant of biomass fuel combustion.

可配有ag88环亚娱乐(燃氣)點火燃燒器,實現點火自動化。給料、燃燒、除渣、給水、點火都可采用自動控制,操作非常方便。配有自動清灰裝置,能及時清除受熱面的積灰,保證高效穩定運行。尾部布置有省煤器、也可根據用戶需要布置空氣預熱器。相對傳統的熱風爐,熱風爐效率更高,排煙溫度低。

Hot blast stove can be equipped with fuel (gas) ignition burner to realize ignition automation. The feeding, combustion, slag removal, water supply and ignition of hot blast stove can be controlled automatically, and the operation is very convenient. Hot blast stove is equipped with automatic ash cleaning device, which can remove the ash deposited on the heating surface of hot blast stove in time and ensure the efficient and stable operation of hot blast stove. The economizer is arranged at the rear of the hot stove, and the air preheater can also be arranged according to users' needs. Compared with the traditional hot stove, the efficiency of the hot stove is higher and the exhaust temperature is low.

采用高效保溫材料,熱風爐表面溫度低,散熱損失可以忽略不計。嚴格按中國國家規範和標準生產,所有受壓部件均采用優質熱風爐鋼材。每台熱風爐出廠前都要經過嚴格的檢驗和測試,包括水壓試驗和X射線檢測。設置有人孔、檢查門、觀火孔等,維護保養十分方便。的最大特點是︰節能、環保,且安裝使用方便。

With high efficiency insulation material, the surface temperature of the hot stove is low, and the heat loss can be neglected. According to China's national standards and standards strictly, all pressurized parts are made of high quality hot blast stove steel. Every hot blast stove must undergo strict inspection and test before leaving the factory, including water pressure test and X ray inspection. It is convenient to maintain and maintain manholes, check doors and fire holes. The main characteristics of biomass hot stove are: energy saving, environmental protection, and easy installation and use.

燃料供應

Fuel supply

熱風爐的燃料是BMF燃料,燃料由輸料機送入爐頂料倉,然後由螺旋給料機送入爐膛,均勻散落在爐排上。

The fuel of hot blast stove is BMF fuel. The fuel is fed into the top bin by the feeder, and then into the furnace by the screw feeder, evenly scattered on the grate.

燃燒過程

Combustion process

燃料被螺旋給料機送入爐膛,在此處由于高溫煙氣和一次風的作用逐步預熱,干燥、著火、燃燒,此過程中析出大量揮發分,燃燒劇烈。產生的高溫煙氣沖刷熱風爐的主要受熱面後,進入熱風爐尾部受熱面省煤器和空氣預熱器,再進除塵器,最後經煙囪排入大氣。未氣化的燃料邊向爐排後部運動,直至燃。 詈笫O碌納倭炕以淙  藕竺嫻某。

The fuel is fed into the furnace by the screw feeder, where it is gradually preheated, dried, ignited and burned due to the action of high temperature flue gas and primary air. During this process, a large amount of volatile matter is precipitated and burned intensely. After the high temperature flue gas washes out the main heating surface of the hot blast stove, it enters the economizer and air preheater of the heating surface at the tail of the hot blast stove, then enters the dust collector, and finally discharges into the atmosphere through the chimney. The non-gasified fuel moves towards the back of the grate until it burns out. Finally, a small amount of residue falls into the slag removal port behind the grate.
