Diagonal windCrossbeam grateFilm is an application inCrossbeam grateA new type of inclined air outlet on the topCrossbeam gratePlate, this type of grate plate is different from the existing grate plate in that it has a vertical upward airflow direction and an oblique airflow directionCrossbeam grateThe air outlet direction of the ventilation hole of the sheet has a certain angle with the vertical direction. The angle between the ventilation holes of this grate and the vertical direction provides a certain horizontal velocity for the grate ventilation when it leaves the grate, which is conducive to the horizontal diffusion of ventilation in the coal seam, improving the mixing effect of coal and air, and reducing the amount of coal leakage in the grate.
