To facilitate ash removing, the grate is designed to be manual or automatic, so that the ash falls into the dust collector with the grate movement. Bottom feed type pellet burner. Bottom feed type burners are originally used for the burning of wood chips, then they gradually become usable for biomass pellet fuel.
The grate has the types of fixed type, mobile type, reciprocating type, vibration type and lower feeding. 1. Fixed Grate The grate is generally strips or plates, and is fixed on the bottom of the hearth or combustion chamber by a frame mounted around it.
Grate boiler: Coal or other solid fuels like biomass (about a few millimeters in diameter) are fed into the boiler from a hopper or conveyor belt. They move across a grate, which has air flowing from underneath into the boiler. The fixed carbon burns on the grate, and the volatile gas burns in the space above.
