Abstract
The method of the present invention features the provision of a plurality of segmented chambers formed in an enclosure. Particulate fuel and air are introduced into one of said chambers during start-up and low loads, and, as the load increases, fuel and air are introduced to additional beds. The air velocity is controlled so that bubbling fluidized beds are initially established in the chambers and, as the load increases, the air velocity is increased to establish a circulating fluidized bed in each chamber.
