Gas cooker with burner of array polyhedral burner

Abstract

A burner at least comprises an array polyhedron distributor and a burner main body. An array polyhedron is formed by a plurality of inclined planes, curved surfaces or composite curved surfaces in array distribution along two sides of the top the array polyhedron distributor; or an array polyhedron is formed by a plurality of inclined planes, curved surfaces or composite curved surfaces in array distribution along the single side of the top the array polyhedron distributor; every inclined plane, every curved surface or every composite curved surface, which forms an array surface, is at least provided with one row of first holes; fire hole fluid channels between the first holes are parallel to each other, and the air flow directions of fire hole outlets are consistent; included angles between the axes of the fire holes and the horizontal plane are no larger than 90 degrees; and air flow channels are arranged between adjacent surfaces. An array parallel flame combustion technology is adopted, the effects of improving air supplementation and burning temperature fields, restraining NOx generation and improving heat efficiency of a cooker are remarkable, and the burner has the advantages of being high in power, novel and unique in design and competitive in cost.

Description

technical field [0001] The invention relates to a gas stove, in particular to a gas stove with a burner of an array polyhedron fire distributor. Background technique [0002] At present, the thermal efficiency of embedded gas stoves on the market is generally lower than 55%. In order to improve the energy-saving effect of gas stoves, the inner flame burner which concentrates the flame to the central area of ​​the burner has received widespread attention. In the existing internal flame burner, the fire holes are mostly distributed along the circumference of the burner, and between adjacent fire holes, the flames will intersect along the exit direction. Although this kind of combustion structure can significantly improve the thermal efficiency of the stove, it is more difficult to control the content of CO and NOx in the flue gas than the non-inner flame burner; the power of the gas stove with the inner flame burner is generally lower Small, it is difficult to meet the marke...

AI Technical Summary

Problems solved by technology

Although this kind of combustion structure can significantly improve the thermal efficiency of the stove, it is more difficult to control the content of CO and NOx in the flue gas than the non-inner flame burner; the power of the gas stove with the inner flame burner is generally lower Small, it is difficult to meet the market demand for high-power gas stoves; to increase the power of the internal flame burner, it is often necessary to increase its overall size. and material costs are clearly uncompetitive
