Grate

From Wikiwaste

Grate-type incinerators are suitable for large irregular-shaped wastes, which can be supported on a stationary or moving alloy grate that allows air to pass through from underneath into the waste. The primary furnace is followed by a secondary combustion chamber, where additional air and fuel are added, to ensure complete destruction of all toxic emissions. These types of incinerators are widely used for the incineration of solid mixed municipal waste (MSW), but can also be applied to sewage sludge, clinical waste, and commercial and industrial waste[1]. They generally have limited application for hazardous waste incineration due to the high temperatures required in the chamber which could have adverse effects the structure of the grate[2].
