ABSTRACT:
A circulating fluidized bed combustion process which uses a sorbent to react with sulfur oxides employs a process for fracturing the sorbent particles to expose unreacted sorbent in the core of the particles to increase the sorbent utilization. The particles within the circulating bed are fractured by injecting water either as a liquid or as steam.
