Grate waste incinerator 200 t/h

Main equipment

Hopper and feeder

The feeding system consists of a hopper and a feeder. The hopper is fitted with a gate that provides a seal while also serving a bridge-breaking function: when waste clumps together and bridges, blocking the hopper, the gate moves to break the bridge. The feeder and gate are driven by hydraulic cylinders. Through periodic reciprocating push-and-pull motion, a set amount of waste is pushed into the incinerator, and the feeder speed can be adjusted according to the incinerator load.

The waste incineration grate is a forward-push, stepped, inclined reciprocating grate. The grate is divided into three stages — drying, combustion, and burnout — with a height difference between each section. As waste falls, it is scattered and broken up, which moves the waste along while preventing the clumping that would cause incomplete combustion. The grate is driven by hydraulic cylinders, and the three sections can be controlled independently so that their movement cycles can be adjusted separately according to the combustion conditions in the furnace. The grate is cast from heat-resistant cast steel, giving it good wear resistance, high-temperature resistance, and corrosion resistance.
