Problems solved by technology

However, in this patent application, the main combustion flame hole is higher than the auxiliary flame hole. Under the condition of small load, the length of the auxiliary flame may be insufficient, and it is difficult to intersect the main flame well. At this time, the stability of the flame is relatively poor

Abstract

The embodiment of the invention discloses a fuel gas premixing burner and a fuel gas water heater. The fuel gas premixing burner has the burning direction and can be in matched connection with a premixing cavity arranged on the upper stream in the burning direction of the fuel gas premixing burner, and fuel gas and air can be burnt through the fuel gas premixing burner after being mixed in the premixing cavity. The fuel gas premixing burner comprises a burner base plate and main burning holes formed in the burner base plate. Auxiliary burning holes formed in the down streams of the main burning holes in the burning direction are further formed in the burner base plate. Auxiliary flames of the auxiliary burning holes and main flames of the main burning holes are intersected. According to the fuel gas premixing burner and the fuel gas water heater, the main burning holes are formed in the upper streams of the auxiliary burning holes in the burning direction, as the main flames are normally larger than the auxiliary flames in size, the main flames are arranged on the upper streams of the auxiliary flames, the auxiliary flames and the main flames are easily intersected, and then the flame stabilizing effect is achieved through opposite burning of the auxiliary flames and the main flames.

Description

technical field [0001] The present application relates to the field of water heaters, in particular to a gas premix burner and a gas water heater. Background technique [0002] Premixed combustion refers to the mixing of gas and air in the premixed chamber, and the mixed gas is burned on the burner. The structural design of the burner has a great influence on the combustion of the mixed gas. Existing burners, such as iron-chromium-aluminum wire mesh burners, are burners covered on the surface of the supporting element with a metal mesh made of a special material. The flame is attached to the surface of the metal mesh, which has a large porosity, good flame stability, a large adjustment ratio, and a good level of pollutant emissions. However, due to the particularity of the wire mesh, its manufacturing process is complicated and the cost is high. [0003] In order to reduce the difficulty of manufacturing, some flat-plate burners with simple manufacturing processes have be...
