The present invention discloses a burner including a shell, a number of fuel-air mixing elements, and a metal fiber cover. The burner is received in the shell for mixing introduced air and fuel gas to generate a fuel-air mixture. The metal fiber cover is received in the shell and positioned above the number of fuel-air mixing elements for burning the fuel-air mixture thereon. By employing a number of fuel-air mixing elements, the fuel gas and air can be completely mixed to a predetermined stoichiometric proportion before reaching the metal fiber cover, thereby achieving a full combustion on metal fibers and reducing the generation of nitrogen oxides accordingly. |
