Abstract
The utility model relates to a burner used in an H-shaped gas heating water heater. The burner comprises an ejecting pipe, a mixing chamber and a burning fire orifice plate, wherein the ejecting pipe is connected with the mixing chamber, a flow equalizing gap is arranged at the top of the mixing chamber, and the burning fire orifice plate is arranged at the top of the mixing chamber. Compared with the prior art, by using the burner, the thermal load can be increased by about 20%, the carbon monoxide emission can be reduced by 100-150 PPm, the noise can be reduced by 4-6 db, and the testing efficiency of a same machine can be increased by 2-4%.
Description
Technical field
The utility model relates to a kind of H shape burner, especially relates to a kind of H shape gas-heating water heater burner.
Background technology
The burner fire row (negative-pressure firing) of gas-heating water heater use now is because the user constantly requires to increase single only thermic load of fiery row, so cause former fire row internal flame to increase, carbon monoxide emission concentration increases, thermal efficiency decline, and noise increases.We improve former fire row at above defective.By the burning orthogonal test of designing and calculating and different structure size, determined that gas and hot water heating stove of new generation arranges with burner fire.We are called H type fire row novel fire row, have improved former burner fire row's combustion conditions and performance.
The utility model content
The purpose of this utility model is exactly to provide a kind of H shape gas-heating water heater burner that increases thermic load, reduces CO emission for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of H shape gas-heating water heater burner, it is characterized in that this burner comprises induction tunnel, mixing chamber and burning fire hole plate, described induction tunnel is connected with described mixing chamber, the current-sharing slit is offered at this mixing chamber top, and described burning fire hole plate is arranged on the top of mixing chamber.
The angle of described induction tunnel front end is 6 ° 20 ".
Described induction tunnel length is more than or equal to 73mm.
One side of described mixing chamber is a convex structure, and its arc radius is enough to steering current and produces rotation effect.
Described current-sharing slit is a strip structure, has replaced former salient point damping structure, and the width in current-sharing slit is pressed the irregular increase gradually of equal pressure principle from left to right.
The top of described burning fire hole plate is provided with burner, evenly is provided with many group fire holes on this burner.
Compared with prior art, the utlity model has following advantage:
(1) can increase thermic load about 20%;
(2) carbon monoxide emission can reduce 100-150PPm;
(3) noise decline 4-6db;
(4) can increase 2-4% with the machine test efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of burning fire hole plate;
Fig. 3 is the structural representation of current-sharing seam.
1 is that induction tunnel, 2 is that mixing chamber, 3 is that burning fire hole plate, 31 is that burner, 32 is that fire hole, 4 is the current-sharing slit among the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of H shape gas-heating water heater burner, its structure as shown in Figure 1, this burner comprises induction tunnel 1, mixing chamber 2 and burning fire hole plate 3, induction tunnel 1 is connected with mixing chamber 2,4 ° 32 " changing into 6 ° 20 " that the angle of induction tunnel 1 front end is original, thereby can reduce the injection resistance, also increase the length of induction tunnel 1 in addition, the length of the induction tunnel 1 of use is more than or equal to 73mm.One side of mixing chamber 2 is a convex structure, thereby can produce the rotation mixed airflow by steering current in mixing chamber 2.Add the air flow blending space, change former fire row's laminar flow and turbulent mixture state fully, the air-flow rotation is mixed account for about 80%.It is more complete that combustion gas is mixed with air.Current-sharing slit 4 is offered at the top of mixing chamber 2, and current-sharing slit 4 is a strip structure, and as shown in Figure 3, the width in current-sharing slit 4 increases from left to right gradually, changes the current-sharing method of salary distribution of former pre-mixing gas combustion.Variation with gap size replaces the damping boss, realizes prolonging the uniform distribution of fire hole direction air-flow, thereby keeps the uniformity of flame height to reduce the static pressure loss, thereby the ejector capacity that adds large-scale combustion fire hole plate 3 can adapt to the requirement that thermic load increases.The top of mixing chamber 2 is provided with burning fire hole plate 3, the structure of burning fire hole plate 3 as shown in Figure 2, the top of burning fire hole plate 3 is provided with burner 31, evenly is provided with many group fire holes 32 on this burner 31, thereby increases steady flame effect.
Claims (6)
