PARTIAL COMBUSTION OF SOLID FUEL WITH FLY ASH RECYCLE

摘要

In a process for the partical combustion of finely divided solid fuel, fly ash entrained by the formed product gas is recirculated to the combustion space. The fly ash is thereto separated from the product gas, mixed with fresh solid fuel, brought together with the fresh solid fuel in a fluidized state by injecting a gaseous medium and recirculated to the combustion space.
