ABSTRACT:
Solid municipal waste refuse is pre-treated by partial burning in a moving grate hot carbonizer furnace and then further burned on a reciprocating step-grate stoker in the same furnace chamber. Limited amounts of air are fed to the waste through the grates to avoid the formation of hot spots in the burning material, thereby preventing the formation of clinkers and restricting the burning of volatile matter in the refuse. Hot low-Btu gas exhausted from the furnace chamber is burned in a boiler.
