  我公司生产的wRF系列燃煤热风炉是以煤为燃料进行热能交换,输出高温洁净热空气的供热装置,WRF系列热风炉,是我公司经国家农业部专家课题组推荐,并进行改革创新自行设计的系列新产品。具有结构简单、安装方便、性能稳定可靠,同时具有新型高效节能等特点,是用户信得过的产品,目前已形成系列批量生产。

 

  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

  炉排由炉排减速机带动,使炉排不斷由前向后移动。
  煤由上煤机提至煤斗内,由煤闸板调节到相应的厚度,均匀地平铺在炉排上,随炉排的移动不断向前,接受炉内的高温辐射,依次完成预热、烘干、着火等阶段,直至燃尽,最后炉渣落入排渣机内,由排渣机排出炉外;燃烧所产生的高温烟气经沉降后室沉降再经过烟道进入换热器管组,与管外的冷空气换热,交换后的低温废烟气由引风机经烟囱排入大气,冷空气经热交换后变为高温空气,完成换热过程,由于空气与烟气是通过管壁间接换热,所以换热后的空气是干净、无污染的。

 

1、本热风炉由燃烧室,沉降室,换热器等组成。系统包括鼓风机,引风机,上煤机,除渣机,烟管道及烟囱等。
2、该机采用链条炉排,机械上煤,机械排渣,提高了该机的机械化程度,减轻了操作工人的劳动强度。
3、燃料可用性好。适用‖、Ⅲ类烟煤,无烟煤,也可适用于秸秆、稻壳等生物质燃料。
4、操作简单方便,运行安全可靠,燃烧充分,热效率高,可达75%以上。
5、采用全钢结构列管换式热器,克服了以往换热器漏火现象的发生,不漏火,杜绝了火灾事故的发生。
6、炉排减速机与鼓风机采用变频电机,且与温度传感器互锁,温度波动小于±3℃,高效节能。

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系列燃煤热风炉  /  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.
