Problems solved by technology

Its disadvantage is that the flame stability of a single circular hole or rectangular hole is poor. In the case of unstable air supply flow or high-load combustion, it is easier to produce flame separation, and in the case of small-load combustion, it is easier to produce back fire phenomenon

Abstract

The embodiment of the invention discloses a gas premixed burner. The gas premixed burner has a burning direction; an impeller-shaped mixer and a burner substrate are arranged in a burner main body; the impeller-shaped mixer is arranged on the upstream of the burner substrate, so that gas and air are uniformly mixed before burning; a main burning surface is arranged on the downstream of the burner substrate; the main burning surface and the burner substrate are tightly connected in a matching manner; an auxiliary flame burning surface and the main burning surface are tightly connected in the matching manner; a main flame of the main burning surface and an auxiliary flame of the auxiliary burning surface are positioned on the same plane; as the scale of the main flame is greater than that of the auxiliary flame and the air current speed of the main burning surface is greater than that of the auxiliary flame burning surface, the auxiliary flame realizes the effect of stabilizing the main flame; a burning chamber is arranged on the downstream of the main burning surface and the effect of further stabilizing the burning is realized. According to the gas premixed burner disclosed by the invention, a metal mesh is taken as the burning surface; with larger porosity, the metal mesh has low possibilities of being blocked by tiny dust in the air, tempering and floating flame; a fan has higher efficiency.

Description

technical field [0001] The present application relates to the technical field of gas combustion equipment, in particular to a gas premix burner. Background technique [0002] Premixed combustion refers to the uniform mixing of gas and air in the premixed chamber, and the mixed gas is burned on the burner. The structural design and material selection of the premix burner have a great influence on the combustion of the mixed gas. [0003] In order to reduce the emission of combustion pollutants, some metal fiber burners with complex manufacturing processes and high costs have been developed. For example, the Chinese patent with the application number 201420238167 and the patent title "A Metal Fiber Burner for Environmentally Friendly Gas Boilers" proposes a A premixed burner covered with iron-chromium-aluminum fiber on the surface of the support element, the flame is attached to the surface of the metal fiber for combustion, the pores are small, the flame stability is good, i...
