1, combustion characteristics : The furnace used dry reflection technology, combustion using bituminous coal, gas heated by the hot burning coal bed filtration, chimney do not smoke. The chamber used mainly by Wai refractory heat preservation material, high-temperature chamber, with an appropriate amount of coal burning into the wind so that more fully, energy conservation, more suited to the burning anthracite, echo the environmental requirements. 2, energy conservation features : As a depressed being heated face, the gas heater extended stay structure, the low-temperature furnace for cigarettes, 250 degrees around, thermal efficiency 75.5% more. 3, removal features : In the chamber itself, there are four dust landing room combustion gases rising process, the dust in every inertial separation as a result of dust and indoor air collision landed at irregular dust indoor air every time the door opened removal stands up. 4, Chu Hui features : Boilers face in being heated to grey easily, often resulting in heat transfer due to good grey slow, wasting energy. This product can removal, the timely removal of the surface being heated indoor air each dust Jihui. Increase being heated face the heat conduction efficiency, improve thermal efficiency. 5, the provincial industrial and municipal features : Under normal combustion process, as long as the after-burner of coal, coal combustion can be fully, unlike the two-tier Lupai boilers, but also often from Lupai draw down on the lighted charcoal. Letters stoves, Pull Down smoke turned, and new coal stove door open, door closed Chuzha can seal letters stoves.
