摘要
PURPOSE:To preclude air supply from being excessive to a furnace in such a way that vent air separated from particle coal is not directly incinerated but used for transporting particle coal and as primary air, on the other hand it is returned to a particle coal machine, and particle coal under residual pressure is recollected. CONSTITUTION:Part of vent air completed transportation of particle coal from a particle coal machine 1 to a particle coal reservoir 3 is returned again to the particle coal machine 1 for using as outlet temperature control air of the particle coal machine 1, on the other hand residual vent air is used as transporting air for transporting particle coal from the particle coal reservoir 3 to a burner 6. By this process since it is not to directly send vent air separated from particle coal to a furnace or it is merely to send part of it, excessive air is precluded from supplying to a boiler so that it can improve the boiler efficiency and prevent air pollution.
