How does a moving grate incinerator work?
An incinerator is simply a furnace that uses waste as its fuel. The type of waste that’s being burned determines the style of furnace. A normal furnace will have a fixed grate upon which the combustion takes place, and more waste is continually added to keep the fire going. (It’s much like your wood-burning stove, but on a much bigger scale.) As with all combustion processes it’s necessary to blow considerable amounts of air over the waste to provide the oxygen that keeps the combustion process going. In a moving grate incinerator the grate itself is like a large conveyor. As waste is added at one end of the conveyor or moving grate, air is blown in from beneath the gate. This has the effect of lifting the the combustibles off the grate as they move through the furnace, providing superior combustion because of the increased contact time of the air. Moving grate incinerators tend to be more efficient in that they provide better overall combustion of the waste products due to the higher
