===Incineration Grate===

The roles of the [[Incineration|incineration]] [[Grate]] include loosening the materials to be [[Incineration|incinerated]] and transporting the materials to be [[Incineration|incinerated]] in the furnace. The [[Grate]] requires good distribution of the [[Incineration|incineration]] air into the furnace. A primary air blower forces [[Incineration|incineration]] air through the small [[Grate]] layer openings into the fuel layer. More air is usually added above the [[Waste|waste]] bed to complete [[Combustion|combustion]]. The residence time of the [[Waste|wastes]] on the [[Grate]] generally ~~does not exceed more than~~ 60 minutes.

Some fine material (referred to as siftings/riddling) may fall through the [[Grate]] which gets recovered in the [[Fly Ash|bottom ash]] remover or is recovered separately. It can be recycled to the [[Grate]] for repeated [[Incineration|incineration]] or removed for disposal. If the siftings are recirculated in the hopper, care is taken not to ignite the [[Waste|waste]] in the hopper.
