Dry slag remover (Dry slag extractor)Its material is Stainless Steel 304 or 316:

Origin: China

Brand: Qingdao Kechengyi

Dry slag extractor is pulverized coal furnace bottom slag equipment, used for cooling hot slag and transmission. We set the slag well before and slag warehouse equipment after, form a complete set of dry slag discharge system, implementation: collection to primary crushing, conveying and cooling - crushing - storage, discharge the whole bottom slag treatment process on a regular basis.

Air-cooling dry slag removal system of continuous operation for air-cooling Dry slag extractor, continuous fall in high temperature furnace slag machine conveyor belt, high temperature and ash in the low speed conveyor belt movement, the negative pressure (for pulverized coal fired boiler, the normal operation of the furnace negative pressure), a small amount of controlled environment air reverse get inside air-cooling Dry slag extractor, make the ash conveying steel band gradually by the wind cooling, and gradually complete combustion. Cold air sufficient heat exchange with high temperature ash, radiant heat and air will boiler slagging characteristics, ash and slag sensible heat absorption, the air temperature rise to about 300 ~ 400 ℃ (equivalent to the boiler secondary supply air temperature), into the furnace, slag cooling temperature has dropped to about 100 ℃.

Cooling air influence the air of the boiler,in general it is controlled within allowable excess air coefficient, so after heating up the hot air can be transported to the chamber, and affect the normal operation of the boiler is not. Strict but, if the excess air coefficient of boiler, hot air can also be transported to the boiler air supply system, to reuse.

Dry Type Slag Conveyor:

Working Principle:

Under normal boiler operation condition, the hot slag (about 850℃) fell from the bottom ash hopper will be discharged by the bottom ash discharge device to the belt of the steel band conveyor, and move slowing together with belt. Due to the negative pressure of boiler, the cold air will flow into the casing of the conveyor through the air vents to cool the hot bottom ash on the belt and make it re-burn gradually, achieving the heat exchange between the coal air and the hot bottom ash, and then the cold air will absorb the sensible heat of the ash and the heat released by the re-burning ash, and the air temperature will increase to 400-500℃ before entering the boiler furnace. The bottom ash will be conveyed and cooled down to less than 200℃ on the slag conveyor, and then delivered to the follow-up conveying device.
