Abstract
The utility model discloses a high-efficiency rich/lean burner, which comprises a plurality of fire rows, wherein the plurality of fire rows are arranged in parallel at intervals; each fire row is provided with a plurality of flame port groups in parallel; each flame port group comprises a plurality of flame ports which are formed in parallel; fuel gas is burnt through the flame ports to form lean flames; fire row side plates are arranged outside side plates of each flame port group on each fire row at intervals, and the side plates of each flame port groups and the fire row side plates form rich flame ports; the fuel gas is burnt though the rich flame ports to form rich flames; and an upper port of each flame port is provided with a filter screen. The high-efficiency rich/lean burner is quick in ignition, low in noise and stable in flame; moreover, the emission of nitrogen oxides (NOX) can be controlled to be less than 50ppm.
Description
Technical field
The utility model relates to a kind of gas heater and uses burner, relates in particular to a kind of efficient shade burner.
Background technology
Progressively deeply, country advocates the consumer and uses gas heater the energy-saving and emission-reduction policy energetically, and as improving the comfortableness that water heater uses, low combustion noise reaches the top priority that the discharging that reduces NOx is the water heater exploitation.
At present, the water heater on the market because source of the gas calorific value difference causes the jump fire tempering phenomenon serious, influences the water heater safety in utilization.In addition, under the not good situation of flame transmission, when igniting can not be in time with the flame transmission and light remaining fire row, the indoor fuel gas that causes burning increases, and finally causes ignition deflagrating of hot.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of efficient shade burner, and this efficient shade burner not only can pass fire, low noise, flame stabilization fast, and can control NO
XBe emitted on below the 50ppm.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of efficient shade burner; Comprise several fire row that parallel interval is arranged; Said each fire row goes up some groups of flame holes of parallel distribution group; Said every group of flame hole group comprises the flame hole that several are arranged in parallel, and combustion gas forms light flame through this flame hole burning; The outer interval of side plate of all the flame hole groups on said each fire row is provided with fire row's side plate and the two forms dense glory hole, and combustion gas is provided with filter screen through the dense flame of this dense glory hole burning formation at said each port place, flame hole.Like this, through filter screen, combustion gas is sprayed from the flame hole uniformly, and can prevent the tempering that light flame too much causes because of air.
As the further improvement of the utility model, said filter screen is cylindric, and this filter screen is arranged in all the flame holes on the fire row.
As the further improvement of the utility model, said filter screen is covered with the aperture in whole flame hole.
As the further improvement of the utility model, said fire row's side plate is lower than the height of the side plate of adjacent flame hole group with it, more helps the transmission of whole burner flame.
As the further improvement of the utility model, the upper end of said fire row side plate is adjusted air-flow to away from contiguous with it flame hole group side plate bending with this, plays the stable and protective effect of dense flame, prevents jump fire.
As the further improvement of the utility model, said every group of flame hole group comprises six flame holes, wherein between the width in two flame holes be 1.1mm, the width in the flame hole on both sides is 0.7mm.
The beneficial effect of the utility model is: this efficient shade burner is that high-efficiency environment friendly passes fire fast; The gas heater burner of low noise burning and flame stabilization; The 50ppm that is emitted on that this burner bias combustion capable of using is controlled NOx reaches the requirement of GB Pyatyi; Can guarantee that also flame reaches whole fire row rapidly, effectively solve tradition fire row and produce igniting sonic boom etc. more slowly because of passing fire.

The specific embodiment
A kind of efficient shade burner comprises several fire row 1 that parallel interval is arranged, and said each fire row goes up some groups of flame holes of parallel distribution group 2, and said every group of flame hole group comprises the flame hole 3 that several are arranged in parallel, and combustion gas forms light flame 4 through this flame hole burning; The outer interval of side plate of all the flame hole groups on said each fire row is provided with fire row's side plate 5 and the two forms dense glory hole 6, and combustion gas is provided with filter screen 8 through the dense flame 7 of this dense glory hole burning formation at said each port place, flame hole.Like this, through filter screen, combustion gas is sprayed from the flame hole uniformly, and can prevent the tempering that light flame too much causes because of air.
Above-mentioned filter screen is cylindric, and this filter screen is arranged in all the flame holes on the fire row.
Above-mentioned filter screen is covered with the aperture in whole flame hole.
Above-mentioned fire row's side plate is lower than the height of the side plate of adjacent flame hole group with it, more helps the transmission of whole burner flame.
The upper end of above-mentioned fire row side plate is adjusted air-flow to away from contiguous with it flame hole group side plate bending with this, plays the stable and protective effect of dense flame, prevents jump fire.
Above-mentioned every group of flame hole group comprises six flame holes, wherein between the width in two flame holes be 1.1mm, the width in the flame hole on both sides is 0.7mm.
