Abstract
The utility model discloses a combustor for a gas water heater, which comprises a plurality of flame rows and a gas pipeline. Each set of the flame rows mainly comprises a plurality of flame hole sets, each flame hole set includes a plurality of flame holes, lateral plates are respectively arranged on two outer sides of each flame hole set of the respective flame row, a gap is arranged between each lateral plate and the respective outer side of the flame hole set, a portion, at the position of the ends of the respective lateral plate and the respective flame hole, of each gap is communicated with the external, and other portions of the gap are sealed. The gas pipeline includes a light flame gas pipeline and a strong flame gas pipeline, the light flame gas pipeline is communicated with the flame holes in a sealing manner, and the strong flame gas pipeline is communicated with the gap between the lateral plates and the outer sides of the flame holes in a sealing manner. The combustor with simple structure can use strong combustion and light combustion to control emission of nitrogen oxide, can lead flame to rapidly spread to the whole flame rows, and effectively solves the problem of ignition deflagration caused by slow flame spreading in traditional flame rows.
Description
Technical field
The utility model relates to a kind of burner, relates in particular to a kind of gas heater burner.
Background technology
Progressively deeply, country advocates the consumer and uses gas heater the energy-saving and emission-reduction policy energetically, and how improving the comfortableness of gas heater use and the discharging of reduction nitrogen oxide is the main direction of water heater development.
The water heater of Xiao Shouing often can not in time come the flame transmission and light remaining fire row when igniting in the market, and the indoor fuel gas that causes burning increases, and causes ignition deflagrating of hot easily, and is very harmful.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of gas heater burner, this gas heater is emitted on 50ppm with interior and reach the requirement of GB Pyatyi with what burner can utilize that bias combustion controls nitrogen oxide, also can make flame reach whole fire row rapidly, effectively solve tradition fire row and produce ignition deflagrating of hot more slowly because of passing fire.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of gas heater burner, comprise some fire rows and gas pipeline, every group of fire row mainly is made up of some flames hole group, two outsides of every group of flame hole group be respectively equipped with side plate and and the flame hole group outside between have the gap, this gap only communicates with the external world with port, flame hole at side plate, and other parts seal; Described gas pipeline comprises light flame gas pipeline and dense flame gas pipeline, and the sealing of light flame gas pipeline and flame hole is communicated with, and the clearance seal between outside dense flame gas pipeline and side plate and the flame hole is communicated with.
As further improvement of the utility model, described flame hole is V-type and the flame hole that is positioned at middle flame boring ratio both sides every group of flame hole has wide slightly width.
As optimal way of the present utility model, totally seven groups of described flame hole groups, each flame hole group comprises seven flame holes, and the width in three flame holes, centre of each flame hole group is 0.7mm, and all the other are 0.5mm; Gap between the biside plate in described flame hole and the flame hole group outside is 1mm.
As further improvement of the utility model, be provided with the flange of flame hole one side dorsad in described fire row's biside plate port.
As further improvement of the utility model, the height in flame hole is low slightly in the middle of the aspect ratio of described fire row's biside plate.
As optimal way of the present utility model, the low 1～3mm of the height in flame hole in the middle of the aspect ratio of described biside plate.
As further improvement of the utility model, on described dense flame pipeline, also be provided with several trunnion ventholes.
As optimal way of the present utility model, described trunnion venthole is that 4 diameters through hole that is 2mm and each through hole center of circle place straight line and flame hole central axis are 70 degree angles.
The beneficial effects of the utility model are: connect in every group of fire row's group arranged outside gap, flame hole and with gas pipeline, can make each fire row produce deep or light flame separately, and then can control the discharge capacity of nitrogen oxide and reach the requirement of GB Pyatyi, on the other hand, also can make flame reach whole fire row rapidly, make fuel gas buring complete, reduce potential safety hazard.
