Problems solved by technology

[0002] There are generally two types of burners for existing gas stoves. The first type is an atmospheric burner with an ejector tube. The kinetic energy ejected from the nozzle inhales a certain amount of air, forms a mixed gas, and ignites and burns on the flame distribution cover on the burner to generate a Bunsen flame. To achieve complete combustion, a large amount of secondary air must be supplemented, otherwise smoke emissions will occur It is too high and the thermal efficiency is low. The second is an infrared burner with an ejector type. The diameter of the burner head is about Φ140mm. If the primary air is too much, although the smoke emission and thermal efficiency are improved compared with the former, the heat flow is limited, the heat intensity of the burning flame is low, the adjustment range is

Example Embodiment

[0013] Embodiment one, such as figure 1 As shown in the figure, a full premixed energy-saving burner with blowing injection and forced injection includes a main cavity 1, an air pipe 2 connected to the main cavity and a gas pipe 3, and a nozzle 4 connected to the gas pipe, located in the main cavity The fire distributor 5 and the ignition needle 6 at the top of the body are characterized in that a screen 7, a flow regulator 8 and a gas mixer 9 are arranged in sequence between the fire distributor 5 and the nozzle 4 in the main cavity, and the center of the flow regulator It has a trumpet shape with a small top and a big bottom. exist figure 1 For the gas mixer shown, the gas mixer is a cylinder whose diameter corresponds to the inner diameter of the main cavity, and there are a plurality of gas mixing holes 10 that gradually shrink from bottom to top along the longitudinal direction of the cylinder. There is a helical spring 11, and a blowing chamber 12 is set in the premixi...

Example Embodiment

[0014] Embodiment two, such as figure 2 As shown in the figure, a full premixed energy-saving burner with blowing injection and forced entry includes a main cavity 1, a blast pipe 2 connected to the main cavity and a gas pipe 3, and a nozzle 4 connected to the gas pipe, located in the main chamber. The fire distributor 5 and the ignition needle 6 at the top of the cavity are characterized in that a screen 7, a flow regulator 8 and a gas mixer 9 are arranged in sequence between the fire distributor 5 and the nozzle 4 in the main cavity, and the flow regulator In the center, there is a trumpet shape with a small top and a big bottom. exist figure 2 and image 3 The gas mixer shown, the gas mixer is composed of a cylindrical outer ring 10 and a rotating mixed fluid 11, along the outer surface of the mixed fluid 11, there are a plurality of gas mixing holes 13 obliquely from bottom to top. The cavity is provided with a blowing chamber 12, and the screen is at least 5 mm above...

Abstract

The invention provides a blast-injecting forced-advancing full pre-mixing energy-saving combustor which comprises a main cavity, a blast pipe, a fuel gas pipe, a nozzle, a fire distributor and a firing needle, wherein the blast pipe and the fuel gas pipe are connected with the main cavity; the nozzle is connected with the fuel gas pipe; and the fire distributor and the firing needle are arranged at the top of the main cavity. The blast-injecting forced-advancing full pre-mixing energy-saving combustor is characterized in that a screen, a flow fixer and a gas flow mixer are sequentially arranged between the fire distributor and the nozzle in the main cavity; the caliber of the gas outlet end of the flow fixer is smaller than the caliber of a gas inlet end of the flow fixer; the flow mixer is a cylinder of which the diameter corresponds to the internal diameter of the main cavity; and a plurality of gas mixing holes are arranged vertically along the cylinder and the calibers of all gas outlet ends of the gas mixing holes are smaller than the calibers of all gas inlet ends of the gas mixing holes. By adopting the structure, the effects of the high efficiency, the energy conservation and the environment protection are achieved.
