燃油或燃气老化房需要配备燃油或燃气的燃烧器

发布时间:2018-12-12人气:123

燃油或燃气老化房需要配备燃油或燃气的燃烧器,燃烧器产生高温烟气,老化房将高温烟气的热量传导给被加热的空气,被加热的空气吸热后温度升至额定值从热风出口输送给干燥机。燃烧器一般采用自动控温,当实际温度达到额定上限温度时,燃烧器会自动停止燃烧或自动转为小火燃烧;当实际温度降至额定下限温度时,燃烧器会自动重新燃烧或自动转为大火燃烧,升温的速度习通过进风阀来调控。燃油或燃气老化房融于干燥介质较为干净,因此多采用直接加热形式。但由于燃料价格较贵,所以多用于南方,北方使用相对少。

Fuel or gas aging room needs to be equipped with a burner of fuel or gas. The burner produces high temperature flue gas. The heat of high temperature flue gas is transmitted to the heated air in the aging room. After the heated air is absorbed, the temperature rises to the rated value and is conveyed to the dryer from the hot air outlet. The burner usually adopts automatic temperature control. When the actual temperature reaches the rated upper limit temperature, the burner will automatically stop burning or automatically turn to small-fire burning. When the actual temperature drops to the rated lower limit temperature, the burner will automatically reburn or automatically turn to large-fire burning, and the heating rate will be regulated by the intake valve. Fuel or gas aging room is cleaner when melted into dry medium, so direct heating is often used. However, because of the high price of fuel, it is mostly used in the South and relatively less in the north.
