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.
