摘要： A combustor assembly in a coal burning power plant includes a combustor housing that defines a combustion zone in which pulverized coal is burned, at least one burner that introduces pulverized coal into the combustion zone, and an overfire air port that injects air into the combustor housing above the combustion zone, the overfire air port being generally not movable with respect to the combustor housing. The combustor assembly further includes a nozzle assembly associated with the overfire air port. The nozzle assembly includes a flow directing structure disposed within the overfire air port, which flow directing structure is tiltable with respect to the overfire air port to effect a change in a flow direction of the air being injected into the combustor housing through the overfire air port.

摘要： A tower distributor receives a stream of working media including pulverized coal and a carrier gas in a coal burning power plant. The tower distributor includes a wall structure and one or more flow directing members including diverters, vane members, and/or protuberances. The wall structure defines a flow passageway for the stream of working media and includes an inlet and an outlet spaced from the inlet in an axial direction. Each flow directing member is provided to alter the flow of the working media through the tower distributor.

摘要： A fuel injector for use in a furnace causes a primary stream of a carrier gas and fuel to be mixed with heated air, oxygen or a mixture of oxygen and CO2 or re-circulated flue gas, within the injector by a secondary stream of heated air, before the primary stream exits the injector as a fuel stream and flows into a combustion zone of the furnace. The interaction of the primary stream with the heated air of the secondary stream increases stoichiometry at the center of the fuel stream exiting the injector, so as to minimize NOx creation and maximize combustion of fuel in the furnace.
