Description
Technical field
The utility model relates to a kind of kiln burner, relates in particular to a kind of premixed secondary wind compensation burning nozzles.
Background technology
Fuel gas buring uses the combustion system of diffusion type usually in Industrial Stoves, and Yin Qibian burns the mode that mix on the limit, can be abundant inadequately with mixing of combustion air because of combustion gas, and make incomplete combustion.In order to make the burning of combustion gas more be tending towards fully, thoroughly, must strengthen the air quantity of combustion air, promptly strengthen coefficient of excess air, thereby reduced the temperature of burning and the temperature of burner hearth, also reduced the efficiency of combustion of combustion gas.And premixed combustion system is a kind of combustion system that combustion gas and combustion air just have been pre-mixed before burning, because the effect of premix can be so that combustion gas can fully mix with combustion air, thereby do not need too big coefficient of excess air can guarantee that burning fully, thoroughly, thereby the temperature of burning and the temperature of burner hearth have just been improved, also improve the efficiency of combustion of combustion gas, reached the purpose of energy-saving and emission-reduction.Therefore according to the theory of Combustion, premixed combustion must solve the difficult problem of tempering, studies the characteristics of premixed combustion, and work and the task of designing a kind of premix burner that can be applied to industry and safety are extremely urgent.
Summary of the invention
The utility model discloses a kind of premixed secondary wind compensation burning nozzles, can not in industry, use the not far and problem of the temperature difference brought of the technical barrier of premixed combustion and high-temperature flue gas injection in order to solve prior art.
For addressing the above problem, technical solution of the present utility model is: a kind of premixed secondary wind compensation burning nozzles, comprise main body cover, it is characterized in that: described main body cover is provided with secondary wind connector, being provided with end plate in the main body cover is connected with the premix tube connector, the other end is connected with the premix barrel of burning nozzles, burning nozzles or premix barrel are provided with the secondary air separating fabric swatch, premix barrel is stretched out main body cover and is outside equipped with secondary wind mozzle, and the internal diameter of secondary wind mozzle is more than or equal to the external diameter of secondary air separating fabric swatch.
Further, described main body cover is provided with end plate, and end plate is provided with 1 to 2 flame-observing hole.
Further, described burning nozzles are provided with the premixed gas delivery outlet, and the relative premix barrel axis of premixed gas delivery outlet is around axle, external inclined type helical form.
Further, described premixed gas delivery outlet is parallel with the premix barrel axis.
Further, between described premixed gas delivery outlet and premix barrel axis radially angle be 5～20 °.
Further, axial angle is 5～20 ° between described premixed gas delivery outlet and premix barrel axis.
The beneficial effects of the utility model are: by the design of burning nozzles etc., solve the problem of premixed combustion tempering, premixed combustion system can be applied on the Industrial Stoves, and reach the purpose of energy-saving and emission-reduction.

Among the figure: 1-main body cover, 2-secondary wind connector, 3-secondary wind mozzle, 4-premix barrel, the 5-nozzles that burn, 6-end plate, 7-premixed gas delivery outlet, 8-secondary air separating fabric swatch.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Referring to accompanying drawing, the utility model comprises main body cover 1, it is characterized in that: described main body cover 1 is provided with secondary wind connector 2, being provided with end plate in the main body cover 1 is connected with the premix tube connector, the other end is connected with the premix barrel 4 of burning nozzles 5, burning nozzles 5 or premix barrel 4 are provided with secondary air separating fabric swatch 8, and premix barrel 4 is stretched out main body cover 1 and is outside equipped with secondary wind mozzle 3, and the internal diameter of secondary wind mozzle 3 is more than or equal to the external diameter of secondary air separating fabric swatch 8.
Described main body cover 1 is provided with end plate 6, and end plate 6 is provided with 1 to 2 flame-observing hole.
Described burning nozzles 5 are provided with premixed gas delivery outlet 7, and premixed gas delivery outlet 7 relative premix barrel 4 axis are around axle, external inclined type helical form.
Described premixed gas delivery outlet 7 is parallel with premix barrel 4 axis.
Between described premixed gas delivery outlet 7 and premix barrel 4 axis radially angle be 5～20 °.
Axial angle is 5～20 ° between described premixed gas delivery outlet 7 and premix barrel 4 axis.
At first combustion gas is mixed according to a certain percentage with combustion air before use, again the premixed gas that mixes is delivered to burning nozzles 5 places by premix barrel 4, and premixed gas passes through axially and the helical form ejection by the premixed gas delivery outlet 7 that is provided with on the burning nozzles 5.And combustion air passes through in the secondary wind connector 2 inflow main body covers 1 by the conveying of pipeline, and by being connected secondary wind mozzle 3 on the main body cover 1 to the output of burning nozzles 5, convert fine flow during the secondary air separating fabric swatch 8 that on by burning nozzles 5 or premix barrel 4, is provided with to, the combustion air fine flow then fully mixes at outer with the mixed in advance premixed gas of burning nozzles 5, then makes the fuel gas buring also sufficient combustion that gets up by manual or automatic igniting at last.And the combustion gas by the premixed gas delivery outlet 7 of axial distribution on the burning nozzles 5 makes high-temperature flue gas quicken ejection at axis direction when burning, spiral helicine premixed gas delivery outlet 7 then makes high-temperature flue gas stir the interior flue gas of burner hearth better, makes burner hearth reach samming.Can make farther and more lasting that high-temperature flue gas can spray by above-mentioned setting, and make the design of premixed gas fractional combustion, thereby make more abundant, the safer the purpose of this utility model that reaches of premixed combustion by the compensation of secondary wind.
