Abstract
The utility model provides a low-pressure high-efficient gas burner. The utility model is characterized in that: by the principle of that the air is heated by the burning gas and the gas burns altogether with the air after joined with the heated air, an air jet nozzle is designed as a hollow shape opened at the upper part and is installed vertically; the lower part of the air jet nozzle is communicated with an inlet pipe; the periphery of the upper part of the middle of the air jet nozzle is provided with a hollow gas jet nozzle whose upper part is provided with a gas jet hole; the cavity of the hollow gas jet nozzle is communicated with a gas inlet pipe. Having the advantages of safety, energy saving, strong fire and high thermal efficiency, the utility model can be produced alone as a burner and a stove.
Description
Technical field
The utility model relates to a kind of low-voltage high-efficiency gas burner that is used for combustion gas.
Background technology
The burner for gas stove that existing hotel, restaurant use generally is to adopt the mode of air blast air blast to burn, and the thermal efficiency is low, and power consumption is big, and firepower not Enough is violent, does not satisfy the requirement that catering trade will be robbed speed the time of striving, and also has potential safety hazard.
Summary of the invention
The purpose of this utility model just provides a kind of energy-saving safe, and firepower is violent, the low-voltage high-efficiency gas burner that the thermal efficiency is high.
Solution of the present utility model is such: utilize the combustion gas of burning that air is heated, air after the heating is added the principle that makes air and the common burning of combustion gas, the air nozzle of design is the hollow form that top has at least one hole, vertically install, the air nozzle bottom is communicated with the air input pipe; The hollow gas nozzle of top band gas jet orifice is installed in the periphery of air nozzle middle and upper part, and hollow gas nozzle inner chamber is communicated with gas inlet pipe.
The utility model has the advantages that energy-saving safe, firepower is violent, thermal efficiency height.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is first kind of embodiment of the present utility model.
Accompanying drawing 2 is second kind of embodiment of the present utility model.
Accompanying drawing 3 is to adopt the utility model to make the structural representation of cooking stove.
The specific embodiment
In structure shown in the accompanying drawing 1, described gas nozzle 3 is to be round to entangle air nozzle 2; The lower end of air nozzle 2 is connected with the sealing of air input pipe 1 external diameter, and the mouth that open the upper end is aperture 5, and in the present embodiment, air nozzle 2 upper ends have a plurality of apertures 5; Air nozzle 2 top apertures 5 are higher than gas jet orifice 4.
In structure shown in the accompanying drawing 2, described gas nozzle 3 is to be round to entangle air nozzle 2; The lower end of air nozzle 2 is connected with the sealing of air input pipe 1 external diameter, and the mouth that open the upper end is aperture 5; The space mounting that surrounds at air nozzle 2 tops and gas nozzle 3 has vertical combustion barrel 6, and gas nozzle 3 bottoms are connected with the location-plate 8 that has the hole, and combustion barrel 6 bottoms and location-plate 8 upper surfaces are gapped.In the present embodiment, the described location-plate 8 that has the hole is wide-bores, is enclosed within air nozzle 2 places and forms the gap, constitutes air duct; Location-plate 8 air nozzle 2 that also can directly be locked leaves at least one hole and forms air duct on location-plate 8.
Combustion gas of the present utility model is a low-pressure fuel gas, so very safe, the combustion air pressure of supply should be greater than combustion gas pressure.When combustion gas and air were upwards sprayed by its spray orifice, both mixed and completing combustion mutually, and formed one strong flame and spray to the bottom of a pan that places on the kitchen range.Because use low-pressure fuel gas, and burning fully, flame washes away effectively the bottom of a pan, heat exchange is good.A plurality of sets of burners are combined into a large-scale combustion device use, can obtain bigger thermic load, and adapt to different needs.
The utility model is installed in the burner hearth, is exactly the burning cooking stove shown in the accompanying drawing 4.
In the accompanying drawing, each parts label is: the 1st, and air input pipe, the 2nd, air nozzle, the 3rd, gas injection Mouth, the 4th, gas jet orifice, the 5th, aperture, the 6th, combustion barrel, the 7th, gas inlet pipe, the 8th, location-plate, The 9th, crater, the 10th, combustion chamber, the 11st, burner hearth cover, the 12nd, heat-insulation layer, the 13rd, furnace enclosure.
