Grate waste incinerator 50 t/h
The main equipment of the 50t/h grate incinerator comprises the feeding system, the grate and the ash and slag system, configured for the municipal solid waste incineration process. Waste passes continuously through feeding, combustion and slag discharge, and the grate is the core part that controls combustion.
Feeding system
The feeding system consists of a hopper and a feeder. A gate inside the hopper seals the hopper and also breaks bridging: when waste balls up and bridges over the hopper, the gate movement clears it. The feeder and gate are driven by cylinders and push a set amount of waste into the incinerator in periodic reciprocating strokes; the feeder speed can be adjusted to the incinerator load.

Grate
The waste incineration grate is a forward-push stepped inclined reciprocating grate divided into drying, combustion and burnout stages, with a height drop between stages so that falling waste is broken up and pushed forward without agglomerating and burning incompletely. The grate is driven by hydraulic cylinders, and the three stages can be controlled independently with their movement cycles adjusted to the combustion state. The grate is cast from heat-resistant cast steel and resists wear, high temperature and corrosion.
Ash and slag system
The ash and slag system consists of the under-grate ash hopper (which also serves as an air chamber), a horizontal ash conveyor and a slag remover. The small amount of fine ash from combustion falls through the grate gaps into the hopper and collects in the horizontal ash conveyor; the main slag is pushed from the burnout grate into the slag drop hopper and then, together with the fine ash, enters the wet slag remover. All ash and slag is carried by the slag remover to the slag pit.
Process features
The equipment is simple in structure, easy to operate and convenient to maintain; the grate resists high temperature, corrosion and wear and needs few replacements. Air distribution across the grate is uniform, combustion is even and complete, and the heat loss on ignition is ≤5%. The equipment is modular, easy to install, quick to build and fully automated.
