  • Lean premix burner having center gas nozzle
    Patent number: 9841189
    Abstract: A lean premix burner has a center fire nozzle, which includes radial gas outlets and a ring of outlets. The gas outlets from the center fire nozzle are fed from a manifold. The center fire gas is controlled separately from the main gas supply, which has several advantages, including enhanced turn down capability.

  • Three stage low NOx burner and method
    Publication number: 20050053877
    Abstract: The present invention is an air-staged low NOx burner 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 NOx staged combustion.
