Product Introduction

A new generation of intelligent high-effect environment-friendly products put forward by our company, which have developed from and taken good advantage of dry-type ash-disposal coal furnace , in which patent deslagging structure is use.

Characteristics: special ash pan, furnace wall always protected by slags, strong effect of slag damaging, slag loosing and ventilation, disposing fundamentally the concept that gas furnace is the same as pressure vessel, heating temperature auto-controlled

Widely used in the environment-friendly and energy-saving technological renovation of gas-processing heating furnace, gas forging furnace, gas crucible furnace, gas mold furnace, grilled ladle gas furnace, sand resin heating gas regenerater, glass melting gas furnace, ceramic gas furnace, as well as smoke exhausting refractory kiln and tunnel kiln

Convent to remove slags: QM-2 wet-type slag removing coal classifier series if placed on ground level, ashes can be disposed conveniently, and humane operation is guaranteed

Applying to continual and cyclical manufacturing at the same time 24 hours a day of continuous work, without stopping to remove slags a Java-air distribution, once-and-for-all air distribution

Easy to operate: coal adding time by the temperature degree indication at the gas exit, needless of operation experience

Long service time: a unique pagoda-style heat-resistant cast iron furnace grate with once-and-for-all air distribution at the same time cooling the grate, the temperature of which maintained at between 150 and 25℃and the service time of the grate largely extended

Maintenance easy: all the components of the furnace body are weld parts, so one welder is enough to complete furnace maintenance on the spot and the repairing time is short if a hole is reserved in advance from which the repairman can enter conveniently, all the repair work can be done inside without dismantling the body and 8 hours is enough to finish the all maintenance tasks which will not affect the peak production

Safer to use: safety is the lifeline of the enterprise, so the safety of the equipment chosen has been paid closest attention at all the slag removing places of QM-2 coal grasifier, extensive waterseal explosion preventing grooves are set pervasively at the time of pressure rising, the pressure can be released in time and the explosion protection is delicate and effective

This is the first safety control.

The second safety control is dedicated gas releasing and exhausting equipment, which should be opened when the furnace stops in order to exhaust the gas gathered in the main pipe and prevent the gas from being sucked back into the bore to explode when meeting fire

Uniform combustion: it has strong ability to break slags, which drop evenly along the circle of the slag pan, coal layers move downwards and does not lead to uneven coal burning as a result of the uneven seam density of coal
Uniform coal distribution: at the coal adding place spacing devices were installed to prevent the cone valve from deviating resulting in uneven coal burning

Special pagoda-type grate ventilation system, with more uniform air distribution, more uniform and thorough combustion, direct combination of vapor acting as gas agent with air, vapor used more completely and classification rate improved more efficiently to over 90%


1.Energy-saving and environment-friendly
The calories of reburning 1kg satandardized coal equals to that of 0.6kg gasoline 0.3kg liquefied petroleum gas and 6.5 degrees of electricity.
The smoke emission complies with the GB9078-96 environment-friendly standard.
2.According to your materialcustomized design
Our company can design and produce air heating furnace according to users' requirement.
We also undertake the renovation of all kinds of oil fuel natural gas coal fuel and electric air heating furnace with the heating cost 70% less than electricity 40 to 60% oil 30% gas.
3.Humanized design:
Reciprocating grate cleaner: strong ability to break and loosen slags as well as to ventilate with slim chance of slagbonding.
Special ash grate design: grate protected by low-temperature slags to prolong the grate's service time largely.
Extensive waterseal explosion preventing grooves at the part of ash hopper: apt to react and safe to use.
Combination of air producing and other heating equipment: convenient to control temperature.
Gas produced immediately by burning coal when it is needed: needless to remove ash reduce temperature or add pressure with the manufacturing cost largely reduced.
Fuel adding and slag removing operated by machines: centralized-control easy to handle and low labor intensity.
4.Convenient installation: 
Installed on ordinary ground special ground unwanted.
5.Flexibility assorted with varieties of other heating equipment:
Widely used in the environment-friendly and energy-saving technological renovation of gas-processing heating furnace gas forging furnace gas crucible furnace gas mold furnace grilled ladle gas furnace sand resin heating gas regenerates glass melting gas furnace ceramic gas furnace and the technological renovation of gas corhart smoke exhausting kiln and tunnel kiln as well as the assorted heating source renovation of drying burning and heating equipment whose temperature requirement is below 1350℃.
