Abstract
The invention discloses a burner of an inner flame gas stove, which consists of a burner body and a fire distributer device; an upper layer fire hole and a lower layer fire hole are arranged on the fire distributer device and the direction of the outlets of the fire holes is inward, and an air channel is arranged or not arranged between the upper layer fire hole and the lower layer fire hole; a single inner cavity or two independent inner cavities is or are arranged; the two independent inner cavities are arranged so that the flame at the upper layer and the lower layer can be regulated independently; while the air channel is arranged so that the air supplementation can be more abundant. The burner utilizes multiple-layer fire holes, stratified combustion and multiple-layer cyclonic flame, and has the advantages of large heat flow, fierce fire power, high heat efficiency, low-CO and low-NOx in smoke gas, no fire hole blocking and the like.
Description
Technical field
The present invention relates to the burner of the burner of gas-cooker, particularly a kind of inner flame gas stove.
Background technology
In recent years, inner flame gas stove was saved combustion gas with its thermal efficiency height, more and more was subject to people's attention.But heat flow greater than the inner flame gas stove of 4kW but seldom is difficult to satisfy the demand of people to big firepower inner flame gas stove in the market.
Will further improve the heat flow of inner flame gas stove, precondition is to guarantee that the pernicious gas that combustion position well reaches in the combustion product gases can not exceed standard.And being seen various inner flame gas stove on the present market are subjected to the restriction of burner structure and combustion system, continue to increase heat flow, guarantee that again CO, NOx in flameholding and the combustion product gases do not exceed standard simultaneously, exist bigger difficulty.Do not exceed standard just not saying guarantee CO, NOx in the combustion product gases, only the combustion stablized angle of collateral security removes to increase the fire hole gross area of burner, and many burners all are difficult to accomplish; Should increase heat flow, guarantee flameholding again, increase fire hole gross area best bet and increase the fire hole number exactly, this is trapezoidal for adopting, the burner of rectangle, bar shaped fire hole, also is the thing of difficulty comparatively.
The producer that has is in order to increase heat flow, the taper seat section that has double circular fire hole is set on inner flame combustor, do like this, though can improve the heat flow of burner, but because double fire hole is subjected to structural limitations, replenish air between upper and lower row's fire hole is difficulty comparatively, and the demand in market is satisfied in the raising of heat flow still difficulty.In addition, adopt the inner flame combustor of circular fire hole, fire hole is directly exposed to the burner top, is difficult to the generation of avoiding liquid and other fouls to stop up phenomenons such as fire hole.
