ABSTRACT:
The present invention is an air-staged low NOxburner for firing a gaseous fuel. The burner fires three stages, with the first stage of combustion taking place substantially within a burner cup section of a refractory baffle, the second stage of combustion taking place adjacent to the baffle and downstream of the baffle, and the third stage of combustion within a furnace. The flow of main combustion air adjacent to the baffle creates a negative pressure zone adjacent to the baffle. The present invention is also a method for low NOxstaged combustion.
