Description
Technical field
The present invention relates to a kind of burner, particularly a kind of food and drink burner with the different air supply modes combination.
Background technology
Various food and drink burners on the market are as being categorized as following a few class by air supply modes: (1) injection burner (slow fire type): air is sucked by jet-flow or combustion gas is sucked by air-spray; (2) air blast burner (vigorous fire type): air is sent into combustion system with air blast.(3) natural induced air type burner (slow fire type): air is sucked combustion system by the negative pressure in the burner hearth.But, also there be not the burner of appearance with the different air supply modes combination in the market.Because the burning result of use or the occasion difference of existing above-mentioned various food and drink burners respectively have its advantage or shortcoming on the market, promptly slow fire type food and drink burner can not reach the effect of vigorous fire, and the effect that vigorous fire type food and drink burner is not equally accomplished slow fire.And above-mentioned various food and drink burner is in the loss that all exists heat energy and efficiency in varying degrees: the gas that (1) existing common food and drink burner has plenty of the gas nozzle ejection directly enters the combustion chamber, though the gas that has plenty of the gas nozzle ejection can pass through a cavity of similar plenum chamber momently, but gas nozzle is very near with the gas outlet distance that enters the combustion chamber, when so just causing burning, combustion gas and air do not mix, combustion gas can't fully be burnt, thereby not only can not bring into play combustion efficiency to greatest extent, and in combustion process, can produce a large amount of waste gas, thereby contaminated environment health; (2) existing common injection burner does not force secondary air to replenish, and during burning, flame is long, and it is insufficient to burn, and firepower is little; (3) combustion flame of existing common food and drink burner generation is hollow shape or middle internal heat group form, they can only produce the limited strong pyrosphere of a circle in the bottom of a pan, or at fiery hot spot of rolling into a ball of the bottom of a pan formation, therefore the heating surface area in the bottom of a pan is limited, the heating situation is undesirable, burning velocity is slow, makes energy consumption increase; (4) existing ordinary burner is because the qualification of structure, need adjust large and small fire by adjusting air door, but in practical operation, it is very difficult that the operator will perform this point in the moment of working, and because the needs of cooking food make burner to change between vigorous fire or the slow fire through being everlasting, so ordinary burner are difficult to accomplish this point, it certainly will exchange its required effect for the combustion gas of loss part, so will further produce unnecessary waste gas and reduce operating rate.
Summary of the invention
The object of the present invention is to provide a kind of food and drink burner with the different air supply modes combination, it provides two kinds of different air supply modes in same combustion chamber, with slow fire type food and drink burner and vigorous fire type food and drink burner comprehensively is one, make the user can freely select to adopt slow fire independent burning mode or vigorous fire independent burning mode or slow fire and the common combustion system of vigorous fire, thereby help increasing work efficiency, energy savings, and can adapt to the work requirements of different occasions.
Technical scheme of the present invention is to constitute like this, it comprises the combustion chamber, around the fire-resistant shell around the combustion chamber, lead to ignitron, static pressure one Room in the combustion chamber, be located at first flameholder between static pressure one Room and the combustion chamber, lead to a Room admission line, static pressure two Room of static pressure one Room, the two Room admission lines of being located at second flameholder between static pressure two Room and the combustion chamber and leading to static pressure two Room; Static pressure one Room is communicated with by a Room combustion gas venthole or the groove of being located on first flameholder with the combustion chamber, and static pressure two Room are communicated with by two Room combustion gas ventholes or the groove of being located on second flameholder with the combustion chamber; The import of one Room admission line is connected with the forced-air blast conveying device, and the import of two Room admission lines is connected with the injection conveying device.
During work, when opening the forced-air blast conveying device, the forced-air blast conveying device with air and combustion gas be transported to mix in the Room admission line after, it is indoor then the air/gas mixture that mixes to be sent into static pressure one at a high speed, air/gas mixture is further mixed under the effect of static pressure, afterwards, under the continuation of external force promotes, the air/gas mixture that further mixes enters in the combustion chamber by a Room combustion gas venthole or groove at a high speed, burns under the flame interaction of ignitron.When opening the injection conveying device, the injection conveying device is under the jet current principle effect, with air and combustion gas be transported to mix in the two Room admission lines after, it is indoor then the air/gas mixture that mixes to be sent into static pressure two, air/gas mixture is further mixed under the effect of static pressure, afterwards, under the effect of static pressure, the air/gas mixture that further mixes enters in the combustion chamber by two Room combustion gas ventholes or groove, burns under the flame interaction of ignitron.When forced-air blast conveying device and injection conveying device were all opened, both equal delivery of fuel gas/air mixtures entered the combustion chamber and burn jointly.
Than prior art, the present invention has the following advantages: (1) is owing to provide two kinds of different air supply modes in same combustion chamber, make slow fire type food and drink burner and vigorous fire type food and drink burner comprehensively be one, both combined the advantage that different food and drink burners are had, overcome different food and drink burners shortcoming separately again, make the user can freely select to adopt slow fire independent burning mode or vigorous fire independent burning mode or slow fire and the common combustion system of vigorous fire, thereby can adapt to the work requirements of different occasions; (2) owing between gas nozzle and combustion chamber, be provided with admission line and plenum chamber, make combustion gas enter before the combustion chamber burns, can in admission line and plenum chamber, fully mix, help the abundant burning of combustion gas, help bringing into play to greatest extent combustion efficiency, thereby both improved operating efficiency, saved the energy, can reduce the generation of waste gas again, avoid environmental pollution, help increasing work efficiency; When (3) when starting forced-air blast conveying device and injection conveying device simultaneously, burning jointly, can not only strengthen combustion efficiency greatly, improve operating rate, and the air/gas mixture that carry the injection conveying device in the air source that can also utilize the forced-air blast conveying device to provide forces secondary air to replenish, the drop of the flame that the injection conveying device is produced, it is more abundant to burn, and further improves combustion efficiency.(4) can between slow fire burning and vigorous fire burning, switch easily, when the cooking, control, can reduce the loss of combustion gas again thereby both be convenient to the user.
