我公司生產的wRF系列燃煤熱風爐是以煤為燃料進行熱能交換,輸出高溫潔凈熱空氣的供熱裝置,WRF系列熱風爐,是我公司經國家農業部專家課題組推薦,并進行改革創新自行設計的系列新產品。具有結構簡單、安裝方便、性能穩定可靠,同時具有新型高效節能等特點,是用戶信得過的產品,目前已形成系列批量生產。
The WRF Series coal-fired furnace produced by our company is aheat supply device with coal as the fuel for heat energy exchange from which clean high temperature hot air is output. WRF Series furnace is a series new product of our company recommended by specialist task group of Ministry of Agriculture, it was designed by ourselves through innovation and creation. It has the features of simple structure convenient installation and use, stable and reliable performance meanwhile, it has the features of new type, high efficiency and energy saving, etc. It is a trustworthy product for users, and has formed series batch production
爐排由爐排減速機帶動,使爐排不斷由前向后移動,
煤由上煤機提至煤斗內,由煤閘板調節到相應的厚度,均勻地平鋪在爐排上,隨爐排的移動不斷向前,接受爐內的高溫輻射,依次完成預熱、烘干、著火等階段,直至燃盡,最后爐渣落入排渣機內,由排渣機排出爐外;燃燒所產生的高溫煙氣經沉降后室沉降再經過煙道進入換熱器管組,與管外的冷空氣換熱,交換后的低溫廢煙氣由引風機經煙囪排入大氣,冷空氣經熱交換后變為高溫空氣,完成換熱過程,由于空氣與煙氣是通過管壁間接換熱,所以換熱后的空氣是干凈、無污染的。
1、本熱風爐由燃燒室,沉降室,換熱器等組成。系統包括鼓風機,引風機,上煤機,除渣機,煙管道及煙囪等
2、該機采用鏈條爐排,機械上煤,機械排渣,提高了該機的機械化程度,減輕了操作工人的勞動強度。
3、燃料可用性好。適用‖、Ⅲ類煙煤,無煙煤,也可適用于秸稈、稻殼等生物質燃料
4、操作簡單方便,運行安全可靠,燃燒充分,熱效率高,可達75%以上。
5、采用全鋼結構列管換式熱器,克服了以往換熱器漏火現象的發生,不漏火,杜絕了火災事故的發生。
6、爐排減速機與鼓風機采用變頻電機,且與溫度傳感器互鎖,溫度波動小于±3℃,高效節能。
1.The furnace is composed of combustion chamber, settlement chamber and heat exchange chamber, etc. The system includes blower, fan, coal feeder, residue discharger, flue pipeline, chimney, etc
2.The useing system includes furnace system, electrically-operaed system, wind pipeline system, etc. The machine adopts chain fire grate wite mechanical coal feeding and mechanical deslagging, the mechanization extent of the mechine is improved, the labor strength of operator is reduced
3.Fuel usability good, it applies to Il and Ill category soft coal, and straw and husk and other biomass fuel may also be mixed for use
4.The machine has reasonable structure, simple and convenient operation, safe and reliable operation, ample combustion and high heat efficiency, can achieve 75%
5.Adopts full steel structure, overcome leaking fire, don' t leak fire, ceasing the fire accident.
6.Fire grate speed reducer and blower use frequency conversion motor with the temperature sensor interlock, temperature fluctuations is less than +3 degrees Celsius, high efficiency and energy-saving
WRF系列燃煤熱風爐 / WRF series coal-fired hot stove
The grate is driven by the grate reducer, so that the grate continuously moves from front to back.
The coal is lifted from the coal pulverizer into the coal hopper, adjusted to the corresponding thickness by the coal sluice plate, evenly laid on the grate, continuously moving forward with the movement of the grate, receiving the high-temperature radiation in the furnace, and completing the preheating in sequence. Drying, ignition, etc., until the burnout, finally the slag falls into the slag discharge machine, and is discharged from the furnace by the slag discharge machine; the high-temperature flue gas generated by the combustion settles through the settling chamber and then enters the heat exchanger tube group through the flue. The heat exchange with the cold air outside the tube, the exchanged low-temperature waste flue gas is discharged into the atmosphere by the induced draft fan through the chimney, and the cold air is converted into high-temperature air after heat exchange, and the heat exchange process is completed, because the air and the flue gas pass through the tube. The wall indirect heat exchange, so the air after heat exchange is clean and pollution-free.
