Description
Technical field
The present invention relates to used on civilian, public food and drink burner it is a kind of with combustion gas step-less adjustment excess load supercharging one
The new complete sucking type eddy flow of kind incites flame, closing burning, the environment-friendly type of superpower furnace temperature, efficient and energy-saving combustion system, is particularly used for making
With the booster-type spiral umbrella flame step-less adjustment energy-saving burner and stove used in property various combustion gas far from it.
Background technology
Existing civilian, food and drink is typically all the burner of atmospheric burning type mode with burner, utensil, mainly there is nozzle, injection
Device, head composition, during work, combustion gas under pressure, is flowed out with certain flow velocity from nozzle, into air-breathing collapsible tube,
Combustion gas by itself energy suction primary air, in induction tunnel combustion gas mix with air, then through head fire hole outflow, progress
Burning.It is in place of this burner Shortcomings：（1）Burner is designed by certain gas component, when combustion gas composition
Change and cause its calorific value, severe and combustion characteristics also to change, the thermic load of burner, primary air ratio, combustion
Burning the combustion conditions such as carbon monoxide content in stability, flame structure, flue gas can change, as primary air is slightly adjusted not
When usually there is imperfect combustion.（2）Only premix partial air during burner combustion, rather than all required for burning
Air, therefore thermal intensity of fire port, ignition temperature are restricted, and tend not to meet technological requirement, when thermic load require it is big when, it is necessary to
Increase fire hole, enlarged head size, huge structure is heavy, and consumptive material consumes combustion gas again.（3）Burner head, it is typically all
Formed using iron casting, fire cover is made of cast iron, cast copper or stamping parts, and combustion heat loss is big, uses fire hole after a period of time
Fire cover aoxidizes or deformation, and combustion conditions change, and it is serious imperfect combustion situation occur, not only wastes combustion gas but also pollution ring
Border.For this, people have of interest to new energy-saving gas oven, and Chinese utility model, Patent No. 03254617.3 provides one kind
Whirlwind flame energy-saving burner, is mainly made up of combustion head, flame cover, Gas Pipe, combustion head copper pipe processing into circle, then
4-5 oblique spray orifices are machined with above copper pipe circumference respectively, connect gas inlet pipe below, flame cover is made of cast iron, and is fixed on
Copper pipe burner port periphery, is maintained a certain distance, and combustion gas sprays through oblique spray orifice, is hit on flame cover inner round wall and is rushed mixed combustion shape
Into whirlwind flame, this burner has firepower violent, can improve effect, there is certain energy-saving effect compared with normal atmospheric burner,
But combustion noise is big, frequent plug-hole, it is impossible to normal work, it is not yet generally applicable.
Weak point existing for existing burner in summary, is usually present imperfect combustion feelings in actual applications
Condition, particularly public burner are more serious when using big fire, not only pollute environment, the harm to human body, and waste a large amount of combustions
Gas resource, to user, economic loss is brought to society, burner generalization is studied for this, attached most importance to environmental protection, energy-conservation, improve combustion
Structure is sintered, improves the thermal efficiency, saves the important topic that the energy is present society concern.
The content of the invention
It is a kind of with combustion gas step-less adjustment function, excess load supercharging, the high combustion of burning calorific intensity the invention aims to provide
Burning system, it can effectively improve culinary art effect, save fuel, and can press technological requirement regulation thermic load.
The object of the present invention is achieved like this, and a booster-type is connected or changed on gas burning system or existing burner
Spiral umbrella flame step-less adjustment energy-saving burner and stove, change burner and stove mainly by nozzle housing, nozzle, needle valve, injector,
