Abstract
The utility model discloses a heat accumulation type energy-saving gas nozzle which comprises a gas pipe. End parts of the gas pipe are respectively provided with nozzle units; each nozzle unit comprises a nozzle sprayer which is mounted in the gas pipe; each nozzle sprayer is provided with a nozzle core; an air conduit is also arranged between the nozzle cores of the nozzle units; an injection guiding device is arranged in the air conduit; each nozzle core is internally provided with a heat accumulating body which runs through the outside; and an air inlet is arranged at the outlet of each heat accumulating body, and the other end of the heat accumulating body runs through the nozzle sprayer to stretch into the gas pipe. Through the design of the paired nozzle units of the gas nozzle, so when one nozzle unit is used for combustion, the other nozzle unit is used for heat accumulation, and the two nozzle units are switched for working timely. Compared with the original nozzles, the nozzle disclosed by the utility model has the advantages that the flame temperature field is more uniform, and the service life of the gas pipe is prolonged.
Description
Technical field
The utility model relates to a kind of fuel burner nozzle, the fuel burner nozzle of particularly a kind of efficient, energy-conservation low NOx.
Background technology
Burner is the burner of using on the industrial fuel stove, is used for equipment such as various heat treatment occasions and combustion gas stove, at present since fuel burner nozzle since structure limit; There is the uneven problem of flame temperature field; Cause burning insufficient, both wasted energy, also make the NOx discharging in the smoke components excessive; Therefore contaminated environment is necessary to design the technology that makes new advances to address the above problem.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides the fuel burner nozzle of a kind of efficient, energy-conservation low NOx.
The utility model solves the technical scheme that its technical problem adopted:
A kind of heat storing type energy-saving fuel burner nozzle comprises Gas Pipe, and the end of said Gas Pipe is respectively arranged with the burner unit; Said burner unit comprises the burner shower nozzle that is installed in the Gas Pipe, and the burner shower nozzle is provided with the burner core, wherein also is provided with air conduit between the burner core of each burner unit; Be provided with induction apparatus in the air conduit; Be provided with in the burner core and penetrate into outer heat storage, the exit of heat storage is an air inlet, and the other end of heat storage then runs through the burner shower nozzle and stretches into Gas Pipe.
In order to protect Gas Pipe roasting not bad by high-temperature gas, the end that said heat storage puts in Gas Pipe is provided with insulating inner lining.
In order to protect air conduit, said air conduit is coated with the air housing outward, and this air housing also has scavenge port, and outside air can be got into.
In order to realize automatic firing function, said burner core leans on an end of air inlet to be provided with ignitor.
The beneficial effect of the utility model is: this fuel burner nozzle is through the design of pairing burner unit, and when a burner unit was used to burn, an other burner unit was used for accumulation of heat; And regularly carry out switch operating, and comparing with original burner, the flame temperature field of this burner is more even; The life-span of Gas Pipe obtains prolonging, and air preheating temperature is the highest can reach 1000 ℃, and the exhanst gas outlet temperature can be reduced to 100～400 ℃; Efficient is higher, simultaneously, owing to adopted the oxygen debt combustion technology of band induction apparatus; NOx in the smoke components discharges less than 150ppm, energy-conserving and environment-protective more.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the front view of the utility model.
The specific embodiment
With reference to Fig. 1, a kind of heat storing type energy-saving fuel burner nozzle comprises Gas Pipe 1, and the end of said Gas Pipe 1 is respectively arranged with burner unit 2, usually 2 one-tenth pairing ground, burner unit cooperating at Gas Pipe 1 two ends.Said burner unit 2 comprises the burner shower nozzle 21 that is installed in 1 li of Gas Pipe; Burner shower nozzle 21 is provided with burner core 22; Wherein also be provided with air conduit 23 between the burner core 22 of each burner unit 2, be provided with induction apparatus 24 in the air conduit 23, said burner core is provided with for 22 li and penetrates into outer heat storage 26; The exit of heat storage 26 is an air inlet 27, and the other end of heat storage 26 then runs through burner shower nozzle 21 and stretches into Gas Pipe 1.
The end that said heat storage 26 puts in Gas Pipe 1 is provided with insulating inner lining 4, plays the effect of insulation, and protection Gas Pipe 1 reduces the waste of heat simultaneously.
Be coated with air housing 28 outside the said air conduit 23, this air housing 28 also has scavenge port 29, and outside air can be got into.
Said burner core 22 leans on an end of air inlet 27 to be provided with ignitor 25, to realize the automatic firing function of burner unit 2.
When real work, when burner unit 2 normal combustion were worked, the 2 pairs of flue gases in another burner unit carried out accumulation of heat.When 2 work of a burner unit; Combustion gas gets into from air inlet 27; Get in the Gas Pipe 1 and air mixed combustion through part burner core 22 and burner shower nozzle 21 backs, the combustion gas kind can be natural gas, liquefied gas, town gas, coke-stove gas, high burnt gaseous mixture or producer gas etc.Combustion air is got into by the scavenge port of air housing 28, carries out preheating through heat storage 26, during air can be preheating to 450～1000 ℃.Combustion air carries out mixed combustion through air conduit 23 backs with combustion gas then; The flue gas that burning produces is flowed through Gas Pipe 1 back to burner unit 2, gets into heat storage 26 behind the air conduit 23 through 2 of another burner unit, thereby heat storage 26 is heated; Temperature dropped to 100～400 ℃ after flue gas came out from heat storage 26; Through induction apparatus 24, induction apparatus 24 is incorporated into about 30～70% flue gas in the burner unit 2 of previous work, mixes with normal combustion air then; Thereby realize that last burner unit 2 burns under oxygen debt state; While can also bring heat energy in the Gas Pipe 1 into through the heating combustion air because the flue-gas temperature that injection refluxes is higher than the combustion air temperature at 100～400 ℃, thereby reaches the effect of energy-saving and emission-reduction.
