Mechanisms of bed material agglomeration in the cyclone and the returen leg of a petroleum coke fired circulating fluidized bed boiler

Petroleum coke firing in a circulating fluidized bed boi8ler has sometimes been reported to be associated with cyclone deposit problems and return leg plugging. In this paper we present data which indicates that some of these problems may be due to the calcium rich bed material used during the firing.
