Problems solved by technology

The burner with this structure mainly has the following problems: First, because the combustion surface is a plane, during the heat transfer process, more heat is lost to the surrounding area, so the thermal efficiency of combustion is low, and due to the large excess air coefficient, resulting in The temperature of the combustion flame (especially the bottom of the pot) is not high, and the carbon monoxide and NO x relatively high emissions

Embodiment Construction

[0016] The specific structure and best implementation mode of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] figure 1 Schematic diagram of the structure of the embodiment of the spherical radiation type gas burner provided by the present invention. This embodiment adopts the side air intake mode, and it includes a nozzle 5, an air suction shrinkage tube 4, a diffuser tube 3 and a gas mixing chamber 7. Combustion level 2 above the ejector and mixing chamber. The combustion layer is in a spherical shape and is formed by splicing one or more curved refractory honeycomb panels 1 . It can be known from experiments that the angle (ie spherical inclination angle) α between the tangent line of the intersection point of the combustion plane and the mixing chamber and the horizontal line is 5°-20°. At this angle, the burner has high combustion efficiency and low carbon monoxide and nitrogen oxide emissions, and at the same...

Abstract

The invention relates to partial premixing type flue gas burner. Face of fire layer is in spherical surface prepared by splicing one or more cambered fireproof honeycomb panel. Angle between tangent of point, which is cutting point between faces of fire layer and mixing chamber, and horizontal line is 5-10 degrees. In the invention, particular surface shape reduces too large radiation heat dissipation from face of fire layer, raises thermal efficiency 20% higher than efficiency of traditional burner. Central temperature is higher than 900deg.C. Discharge of carbon monoxide and Nox is less than traditional burner.

Description

technical field [0001] The invention relates to a gas combustion equipment, in particular to a partially premixed gas burner, which belongs to the technical field of combustion equipment. Background technique [0002] At present, the gas burners used in the prior art are mostly partial premixed burners, which are mainly composed of injectors and combustion levels; they are divided into two types: multi-head torch type and honeycomb flameless type, and the combustion level is generally flat. The heat generated by combustion is transferred outward along the vertical direction of the plane. The burner with this structure mainly has the following problems: First, because the combustion surface is a plane, during the heat transfer process, more heat is lost to the surrounding area, so the thermal efficiency of combustion is low, and due to the large excess air coefficient, resulting in The temperature of the combustion flame (especially the bottom of the pot) is not high, and th...
