Abstract
The utility model relates to a fire grate of low nitrogen oxygen combustor used for wall-mounted boiler, which comprises a fire grate body as well as a fire hole sleeve. An induction hole, a venturi tube cavity, a mixing cavity, a distribution cavity, a gas flow seam as well as a heavy fire gas channel are arranged on the fire grate body; the induction hole is communicated with the distribution cavity through the venture tube cavity and the mixing cavity in sequence; the distribution cavity is communicated with the heave fire gas channel through the gas flow seam; a fire hole sleeve is sheathed on the heave fire gas channel of the fire grate body; the fire hole sleeve is provided with a heave fire stabilizing cavity and a heavy fire hole arranged in the inner side as well as a light fire gas channel and a light fire hole arranged at the outer side, as well as a light fire air channel connected with the light fire gas channel; and the heavy fire gas channel is connected with the heavy fire hole through the heavy fire stabilizing cavity; the two sides of the heavy fire gas channel are provided with flow splitting holes; and the flow splitting holes are connected with the light fire hole through the light fire gas channel. The fire grate of low nitrogen oxygen combustor used for wall-mounted boiler has the advantages of simple structure and low cost, realizes low nitrogen discharge based on not changing the original structure of an ordinary wall-mounted boiler, and increases the heat efficiency of the original wall-mounted boiler.
Description
Technical field
The utility model relates to the burner device, particularly relates to the fire row of a kind of wall hanging stove with low nitrogen oxygen burner.
Background technology
The wall hanging stove be a kind of be main energy sources with the combustion gas, heating of cosy house and domestic hot-water's housed device is provided, the heating of wall hanging stove has powerful family's central-heating function, can satisfy the heating demand in many rooms, and the wall hanging stove becomes the indispensable heating equipment of Chinese family just gradually.
Fire row in burner and the burner relates to the critical component of wall hanging stove performance and efficient, it is at present domestic that what generally use is common negative-pressure firing wall hanging stove, its thermal efficiency is lower, and fire row's design can't be applicable to low nitrogen oxygen discharging, and the external low nitrogen oxygen burner that also has only pressure combustion, its fiery row can't apply on the domestic negative-pressure firing device.
Summary of the invention
Technical problem to be solved in the utility model is exactly to provide the fire row of a kind of wall hanging stove with low nitrogen oxygen burner for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: the wall hanging stove is arranged with the fire of low nitrogen oxygen burner, comprise fire row body, this fire row body is provided with ejecting port, the Venturi tube die cavity, hybrid chamber, distribution cavity, gas seam and dense fiery blast tube, described ejecting port is successively through the venturi tubular cavity, hybrid chamber communicates with distribution cavity, this distribution cavity communicates with dense fiery blast tube through the gas seam, it is characterized in that, also comprise the burner cover, this burner cover is sheathed on the dense fiery blast tube position of fire row body, described burner puts to be provided with and is positioned at inboard dense fiery pressure stabilizing cavity, dense burner, be positioned at the light fiery blast tube in the outside, light burner, and the light fiery air duct that links to each other with light fiery blast tube, described dense fiery blast tube links to each other with dense burner through dense fiery pressure stabilizing cavity, the both sides of described dense fiery blast tube are provided with tap hole, and this tap hole links to each other with light burner through light fiery blast tube.
Described burner cover comprises two interior nest plates and two jacket panel, described two jacket panel are positioned at two nest plate outsides, the two ends of interior nest plate and jacket panel all fix with fire row body, constitute dense fiery pressure stabilizing cavity and dense burner between described two interior nest plates, constitute light fiery blast tube and light burner between described jacket panel and the interior nest plate.
Described burner puts and evenly is provided with a plurality of reinforcements.
Compared with prior art, the utlity model has following advantage:
1, simple in structure, cost is low;
2, use fire row of the present utility model, can easily domestic common wall hanging stove be changed into low nitrogen oxygen discharging wall hanging stove;
3, improved the thermal efficiency of existing wall hanging stove.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1～2, the wall hanging stove is arranged with the fire of low nitrogen oxygen burner, comprise fire row's body 1 and burner cover 2, this fire row body 1 is provided with ejecting port 10, Venturi tube die cavity 11, hybrid chamber 12, distribution cavity 13, gas seam 14 and dense fiery blast tube 15, described ejecting port 10 is successively through venturi tubular cavity 11, hybrid chamber 12 communicates with distribution cavity 13, this distribution cavity 13 communicates with dense fiery blast tube 15 through gas seam 14, described burner cover 2 is sheathed on dense fiery blast tube 15 positions of fire row body 1, described burner cover 2 is provided with and is positioned at inboard dense fiery pressure stabilizing cavity 20, dense burner 21, be positioned at the light fiery blast tube 22 in the outside, light burner 23, and the light fiery air duct 24 that links to each other with light fiery blast tube 22, described dense fiery blast tube 15 links to each other with dense burner 21 through dense fiery pressure stabilizing cavity 20, the both sides of described dense fiery blast tube 15 are provided with tap hole 150, and this tap hole 150 links to each other with light burner 23 through light fiery blast tube 22.
Described burner cover 2 comprises two interior nest plates 25 and two jacket panel 26, described two jacket panel 26 are positioned at two nest plate 25 outsides, the two ends of interior nest plate 25 and jacket panel 26 all fix with fire row body 1, constitute dense fiery pressure stabilizing cavity 20 and dense burner 21 between described two interior nest plates 25, constitute light fiery blast tube 22 and light burner 23 between described jacket panel 26 and the interior nest plate 25; Evenly be provided with a plurality of reinforcements 27 on the described burner cover 2.
Principle: combustion gas and primary air enter Venturi tube by ejecting port, in hybrid chamber, enter distribution cavity behind the premix, combustion gas enters dense fiery blast tube by the gas seam then, the tap hole of part combustion gas on dense fiery blast tube enters light fiery blast tube, and entering light fiery blast tube by light fiery air duct, mixes auxiliary air with gas secondary, form light fiery combustion gas mixing gas, become light flame combustion by light burner; Combustion gas in the dense fiery blast tube enters dense fiery pressure stabilizing cavity, carries out the voltage stabilizing diffusion, and evenly flowing out dense burner becomes dense flame combustion, has formed deep or light diffusion combustion by these two kinds of flames and has reached low nitrogen oxygen discharging flue gas.
