Abstract
A method and system for introducing combustion gases to the upper portion of the dense phase or transition portion of a circulating fluidized bed reactor. The combustion gases are produced in a burner external to the dense phase portion of the reactor wherein the burner receives a mixture of liquid or gaseous fuel and air so as to initiate and maintain combustion within the burner. The combustion gases are then quenched prior to entering the dense phase portion of the reactor so as to reduce the temperature of the combustion gases thereby preventing overheating or sintering of the particulate and significant oxidation reduction in the dense phase portion of the reactor.
