Step grate stoker type sewage sludge incineration and power generation …

Sludge is incinerated on top of a stepped fire grate (of cast construction) without using fluid sand as a combustion media. Additionally, the waste heat boiler installed immediately after the step grate stoker furnace cools down the interior walls and flue passage by means of water tube walls to keep the flue passage and other system components from clogging with incinerated ash deposits.

Mitsubishi Power | Circulating Fluidized Bed (CFB) Boilers

Boilers. A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction. Moreover, the fluid sand and fuel issuing out of the furnace are collected

How Circulating Fluidized Bed Boilers Work? - Bright Hub …

2009/2/22 · Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.
