Abstract
The invention discloses a dense-lean combustion burner for a stove, which mainly comprises a nozzle fixing base, an ejector, a stove plate and a burner, wherein a large nozzle is arranged on the nozzle fixing base and is directly opposite to a port of the ejector, the burner is provided with an inner ring burner cap and an outer ring burner cap which are respectively provided with a fire hole, the burner is provided with a first, a second and a third cavities; the outer ring burner cap is provided with an outer ring, a middle ring and an inner ring fire hole which respectively form a dense combustion fire hole, a lean combustion fire hole and a dense combustion fire hole; the ejector comprises an inner ring ejector, an outer ring ejector and a stove plate ejector; and the stove plate is provided with a plurality of small nozzles. Fuel gas reaches the fire hole respectively through each ejector by means of the burner fixing base, and finally forms two rings of dense flame on the outer ring burner cap and forms a ring of lean flame on the middle. The dense-lean combustion burner for the stove has a simple structure, can ensure that air and fuel gas are more completely mixed and combusted completely, thus generation amount of NOX is effectively reduced; meanwhile, the dense-lean combustion burner has large fire power and can meet the traditional stir-frying demands in China.
Description
Technical field
The present invention relates to a kind of burning jamb, relate in particular to a kind of dense-lean combustion burner for stove.
Background technology
Current kitchen range generally adopt atmospheric burning type mode, contain a large amount of nitrogen oxide NO in the waste gas of discharge
x, but cannot effectively reduce NO with existing combustion technology
xtoxic emission, there is technical bottleneck.And nitrogen oxide is very large to the harm of human body, such as, when people are in NO
2content in the air of 0.5ppm, within 3～12 months, just can cause bronchitis and part pulmonary emphysema phenomenon; Be in NO
2content in the air of 5ppm, will feel has great smell; Be in NO
2content in the air of 50ppm, only need within 1 minute, to make people suffocate; Be in NO
2content in the air of 100～150ppm, within 0.5～1 hour, will there are pulmonary emphysema, have dead possibility; Be in NO
2content be greater than in the air of 200ppm, instantaneous with regard to lived danger.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of dense-lean combustion burner for stove, this dense-lean combustion burner for stove is simple in structure, can make air mix more fully with combustion gas, and sufficient combustion, effectively reduces NO
xgrowing amount, meanwhile, this burner firepower is larger, also can meet the quick-fried demand that Chinese are traditional.
The present invention for the technical scheme that solves its technical problem and adopt is:
