Main Equipment of a 200 t/d Grate Waste Incinerator

Main Equipment

Hopper and feeder: The feeding system consists of a hopper and a feeder. The hopper has a gate inside, which ensures sealing while also providing a bridge-breaking function: when waste clumps and bridges to block the hopper, the gate movement breaks the bridge. The feeder and gate are driven by hydraulic cylinders, pushing a certain amount of waste into the incinerator through periodic reciprocating push-pull motion. The feeder can adjust its feed speed according to the incinerator load.

Waste incineration grate: The grate is a reverse-pushing step-type inclined reciprocating grate, divided into drying, combustion and burnout stages. There is a height drop between each grate section; waste falls and is scattered, which pushes the waste forward while avoiding incomplete combustion caused by waste clumping. The grate is driven by hydraulic cylinders, and the three sections can be independently controlled, adjusting the grate movement cycle according to the in-furnace combustion state. The grate is cast in heat-resistant cast steel, with good wear resistance, high-temperature resistance and corrosion resistance.
