Abstract (en)
This present invention relates to an efficient environmentally friendly burner: a low NO x (nitrogen oxide) burner that uses premixed air and gas as fuel and water as medium of heat transfer. Premixed air and gas in this device provides heat for boiler through stabilized combustion. The device consists of burner ports, flame stabilizers, upper and lower water chambers, and a mixing chamber. The burner ports are formed by a number of rectangular tubes with gaps in between that function as passageway for air and gas. The premixed air and gas are equally delivered from the mixing chamber to those gaps and combust as they flow through. Circulation channels for cooling water are designed inside the burner ports and the flame stabilizer to effectively prevent the flashback of flame as well as lower the combustion temperature. A minimized formation of NO x is therefore achieved. The low NO x burner according to the present invention is simple in structure and convenient to use. Compared with traditional premix combustion systems, this device guarantees combustions that are more stable, and it is much less likely to cause flashback of flame or blockage.
