⑴ Raise the coal gate to a high position, and lay a 20-30mm thick layer of coal in front of the grate. Cover the coal with kindling, cotton waste, and other ignition materials. Place a thinner layer of ash in the middle and rear part of the grate to prevent a large amount of cold air from entering.

Ignite the fuel, slowly rotate the grate, and stop the grate rotation once the fire reaches approximately 1-1.5 meters from the front of the furnace chamber.

As the arch temperature gradually rises to the point of igniting new coal, adjust the coal gate plate to maintain a coal bed thickness of 70-100mm, slowly rotate the grate, and adjust the induced draft fan to bring the furnace chamber negative pressure close to zero, in order to accelerate combustion.

But as the coal moves to the second air door, the second stage air door should be appropriately opened. Continuing to move to the third and fourth air doors, the third and fourth stage air doors should be opened sequentially. When reaching the rear air door, since the coal is nearly burned out, the rear air door should be slightly or not opened at all based on the combustion situation.

Once the grate is fully covered with the base fire, increase the coal bed thickness appropriately, and correspondingly increase the air flow, elevate the grate speed, maintain the furnace chamber negative pressure at 20-30 Pa, and strive for complete combustion of the coal bed.
