Abstract
The utility model relates to a kind of gas-fired radiant heating venturi burner, belongs to heating technology field.This burner is formed by connecting by magnetic valve, gas nozzle, Venturi tube and mixed type combustion head successively.This burner makes radiant heating combustion flame lengthen, and avoids radiant tube local temperature too high, and the main radiant section of radiant tube is lengthened, and Temperature Distribution is more even.Venturi tube is increaser, and its initial segment has annular air inlet duct, is convenient to the suction of burning required air.Mixed type combustion head center is main burner port, the secondary burner port that circumference uniform distribution is tiny, and it has steady fire action, and make burning more stable, adjustable range is wider.
Description
Technical field
The utility model relates to a kind of gas-fired radiant heating venturi burner, belongs to heating technology field.
Background technology
Due to hyperthermia radiation heating have that simple installation, comfortableness are strong, energy-conserving and environment-protective etc. a little, the heating of the large spaces such as the workshop of present industrial enterprise adopts hyperthermia radiation heating, more and more normally based on gas-fired radiant heating.The length of flame is shorter, local strength is excessive because flame propagation speed causes for the combustion system of current gas-fired radiant heating, such radiant tube local temperature is too high, and temperature distributing disproportionation is even, heating system is made still to there is radiation intensity inequality, shortcoming that the thermal efficiency is on the low side.
Summary of the invention
For solve problems of the prior art, the utility model provides a kind of gas-fired radiant heating venturi burner, make caloradiance evenly, to improve the comfortableness of the thermal efficiency and heating.
The technical scheme that the utility model technical solution problem adopts is: gas-fired radiant heating venturi burner, it is connected with radiant tube, it is formed by connecting by magnetic valve, gas nozzle, Venturi tube and mixed type combustion head successively, this burner also comprises shell body, described shell body covers on the outside of gas nozzle, Venturi tube and mixed type combustion head, and shell body is connected with radiant tube; The initial segment of described Venturi tube is provided with annular air inlet duct, and the center of described mixed type combustion head is main burner port, the secondary burner port of circumference uniform distribution of mixed type combustion head.
Described Venturi tube is the increaser from gas nozzle to mixed type combustion head direction.
The beneficial effects of the utility model are: this burner is formed by connecting by magnetic valve, gas nozzle, Venturi tube and mixed type combustion head successively.Venturi tube is increaser, and its initial segment has annular air inlet duct, is convenient to the suction of burning required air.By mixing, the pressurization of Venturi tube, effectively can lengthen the length of flame in radiant tube, not only avoid radiant tube localized hyperthermia, and the main radiant section of radiant tube is lengthened, Temperature Distribution is more even.Mixed type combustion head center is main burner port, the secondary burner port that circumference uniform distribution is tiny, and it has steady fire action, and make burning more stable, adjustable range is wider.

Detailed description of the invention
Fig. 1, Fig. 2 and Fig. 3 show a kind of gas-fired radiant heating venturi burner, and it is formed by connecting by magnetic valve 1, gas nozzle 4, Venturi tube 5 and mixed type combustion head 6 successively.This burner also comprises shell body 2, and it covers on the outside of gas nozzle 4, Venturi tube 5 and mixed type combustion head 6, and is connected with radiant tube 3.Venturi tube 5 is increaser, and its initial segment is provided with annular air inlet duct 5a, and annular air inlet duct 5a is as the suction inlet of burning required air.The center of mixed type combustion head 6 is main burner port 6a, its secondary burner port 6b of circumference uniform distribution.
This burner is assemblied in radiant tube heating system usually, is connected with radiant tube 3 by shell body 2.During work, combustion gas is sprayed by gas nozzle 4 after magnetic valve 1, air enters from housing inlet, sucked in Venturi tube 5 from the annular air inlet duct 5a of Venturi tube 5 by combustion gas injection, Venturi tube 5 mixing portion and flaring part fully mixes, after supercharging, main burner port 6a on mixed type combustion head 6 jets out flames in radiant tube, and the length of flame formed like this can fully lengthen.In addition, form local eddy currents district around the secondary burner port 6b on mixed type combustion head 6, contribute to stable burning things which may cause a fire disaster.By mixing, the pressurization of Venturi tube 5, effectively can lengthen the length of flame in radiant tube 3, not only avoid radiant tube 3 localized hyperthermia, and the main radiant section of radiant tube 3 is lengthened, Temperature Distribution is more even; By the steady fire action of mixed type combustion head 6, make burning more stable, adjustable range is wider.
