Abstract:
Aiming at the problem of gas accumulation of a coal bunker, the air duct with circular hole in the wall of the storage bunker is proposed and the ventilation scheme sets up windows at the top of the warehouse wall. The controlling effect of gas accumulation of the ventilation scheme is analyzed by numerical simulation at last. The ventilation scheme is applicable to the gas accumulation control of different coal storage height, which provides a technical reference to gas accumulation control of a coal bunker.
