In view of the properties of Petroleum coke

study and analysis of CFB boilers for burning petroleum coke have been carried out from some aspects

such as combustion

ignition and stabilization of combustion

and burn-up of petroleum coke

as well as slagging in the furnace

supplement of bed-materials

and corrosion etc.

and corresponding technical measures in the design being recommended. The problem of SO 2 emission caused by burning petroleum coke with high sulfer content can be controlled by using CFB boilers

and the corrosion of healting surface can be alleviated through reasonable design of the said heating surface.
