This series of coal gasifiers is a new generation of intelligent highly efficient environment-friendly products put forward by our company, developing from and taking good advantage of dry-type ash-cleaning gas furnace, in which patented deslagging structure is used. Characteristics: dedicated ash tray, furnace wall always protected by slags; strong effect of slag breaking, slag loosing and ventilation; basically abandoning the concept that gas furnace is the same as pressure vessel; heating temperature autocontroled. The gasifier is widely used in the enviroment-friendly and energy-saving technological renovation of gas-processing heating furnace, gas forging 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 exausting refractory kiln and tunnel kiln.
1) Convient to Remove Slags: QM-2 wet-type slag removing coal gasifier series if placed on ground level, ashes can be taken out conviently, and humane operation is garanteed.
2) Applying to continual and cyclical manufacturing at the same time: 24 hours of continuous work, without stopping to remove slags a once-and-for-all air distribution, once-and-for-all air distribution.
3) Easy to Operate: coal adding time depende on the temperature degree indication at the gas exit, needless of operation experience.
4) 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 250℃ and the service time of the grate largely extended.
5) 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 shot; 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 complete all the maintenance tasks which will not affect the peak production.
6) Double Safety Control, Safer to Use：safety is the lifeline of the enterprise, so 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 dedicated and effective. This is the first safety control. The second safety control is dedicated gas releasing and exausting equipment, which should be opened when the furnace stops in order to dis charge the gas gathered in the main pipe and prevent the gas from being sucked back into the bore to explode when meeting fire.
7) More Uniform Combustion: it has strong ability to break slags, which drop evenly along the circle of the slag tray; coal layers move downwards and do not lead to uneven coal burning as a result of the uneven seam desity of coal.
8) More Uniform Coal Distribution: at the coal adding place spacing devices were installed to prevent the cone valve from deviating resulting in unven coal burning.
9) Gasification More Complete: special pagoda-type grate ventilation system, with more uniform air distribution, more uniform and thourough combustion, direct combination with air of vapour which act as gas agent, vapour used more completely and gasification rate improved more efficiently to over 90%.
