Description
Technical field
The utility model belongs to cooking stove, is used for all kinds of gas-cookers, oil range and variously loves and respects the firing equipment that thermal process has flue gas to produce.
Background technology
The common Chinese style in the domestic large, medium and small restaurant of China is fried the structure of stove and the performance of burner, exists following weak point:
One, the burner of usefulness is that combustion gas is advanced on one side usually, with air blast force enter air on one side, the fuel gas buring in the combustion chamber is dangerous, and it is not good to atomize, and has the part combustion gas to be taken away by thermal-flame, and the heat of taking away accounts for the 10%-15% of fuel gas supply total amount of heat.
Two, a part of common Chinese style stove circle of frying the burner top of stove has opening, allows flame flow out along frying pan, otherwise extinguishes because of anoxic.Therefore the heat of taking away from stove circle opening part thermal-flame accounts for the 20%-30% of fuel gas supply total amount.
Three, the stove circle on the burner top of the common Chinese style stir-fry of another part stove does not have opening, must be at the burner hearth inner opening, allow the part combustion gas and the remaining flame of incomplete combustion remove to heat secondary stove, the heat of taking away simultaneously also is the 20%-30% that accounts for the fuel gas supply total amount of heat.
From above 3 explanations, the structure of common stir-fry stove and combustion system are not only wasted fuel, cause the generation of carbon monoxide severe overweight and nitrogen oxide, environment is polluted, but also improved environment temperature, have worsened the environment of back of house.
The combustion system of the gas-cooker of Chu Shouing all is open burning generally in the market, and promptly stone or metal plate for standing a stove on as a precaution against fire exposes, and flame directly contacts with surrounding air during burning, does not have any retaining closed structure and heat reclamation device.The flare of general gas kitchen range is at random unable, and what active force the bottom of a pan is not almost had, and can be described as to edge away, and the heat energy utilization rate is extremely low, and fire is gone hither and thither along the bottom of a pan, and the flare that overflows along the pot limit is taken away a large amount of heats, and it is very serious to cause heat to run off; Because its design defect, the fuel of inside, combustion zone can not well contact with air, causes the incomplete combustion of fuel.So it is low and energy waste is more serious that common kitchen range use efficient.
The most outstanding shortcoming of this combustion system is that heat loss is big, traces it to its cause: the one, owing to be open burning, only some is absorbed by the bottom of a pan in flame radiation, and all the other all are radiated in the environment.The 2nd, except radiation, flame and flue gas are passed to pot to heat with the form of heat convection, but flue gas leave the pot temperature also very high, be generally about 250 ℃, this part heat is wasted.Cooker commonly used at present is to be made by common metal, there is not any heat-insulation and heat-preservation structure, the heat that absorbs in being subjected to thermal process of cooker is used for heating the food except that part like this, remainder then looses in air by the cooker outer wall, Lang Fei heat also is very big in this way, someone once heated a thermos flask water 12min with the immersion heater of a 1000W, heat the water of same volume then with the electric furnace of same power, the boiled 20min that used of water as a result, why like this many power consumption 67% than the former, reason is that the former heats that the keeping warmth space that is a sealing carries out, heat loss is very little,, and latter's portion of hot amount does not obtain reclaiming and just is lost to environment and has suffered.As seen reclaim heat and can save a lot of energy.
Comprehensive survey is learnt through market: the Chinese style of domestic market appearance is at present fried the stove reducing energy consumption and is divided into two classes substantially: a class is the modified burner combustion chamber, it is constant that former Chinese style is fried the stove circle and the structure of stove, this class burner mainly solves the completing combustion problem of fuel in retrofit process, most of unreasonable products structure, service life is short, energy-saving effect is not obvious, about about energy-conservation 10%-20%.Another kind of is the energy-saving appliance that installs an infrared induction on the basis of original Chinese style stir-fry stove additional, be called the electric induction type pot and play the stove device that goes out, the energy-saving effect of this device is also about 20%, because be electronic induction, the environment that the incompatibility kitchen is hot and humid, fault rate is higher, with just having failed after a period of time.Because the food and drink producer used the burner and the energy-saving appliance of this class, can not get economic benefit, progressively eliminated by market.
In addition, high power gas kitchen range and oil range utilize air blast to produce wind-force a large amount of air are sent into the combustion zone, improved the phenomenon of combustion zone inner fuel incomplete combustion, temperature raises to some extent, reduced the waste of fuel, and wind-force blows and hits flare and quickened the heat transmission of fire to the bottom of a pan, efficient promotes to some extent, but the wind that air blast produces is many and loose, and the wind that looses in a large number enters the combustion zone and takes away a large amount of heats then again, causes a large amount of heats by blowing away in vain.Do not reach purpose of energy saving like this, waste fuel on the contrary more.
It is to increase some Synergistic and energy-saving devices on common gas-cooker that the Synergistic and energy-saving kitchen range is also arranged, its unique design allows the air that has intense impact power on a small quantity initiatively enter inside, combustion zone, contain a large amount of oxygen in the air, entering of it makes the flame combustion of inside, combustion zone more abundant, improved the phenomenon of common kitchen range incomplete combustion, reduce the discharging of carbon monoxide, improved the air quality in kitchen; The flame temperature that it produced is high and concentrate strong, flame directly acts on the bottom of a pan, no longer edges away, and can see significantly that flame has extremely strong impulsive force to the bottom of a pan, its impulsive force makes fire be greatly improved to the heat transmission in the bottom of a pan, and firing rate is faster; And in the outer shroud of gas that is with one of combustion zone, the invisible shroud of gas in this road is retained in a large amount of heats in the combustion zone, prevents the loss of heat, makes the temperature in the combustion zone higher, and heat energy obtains better utilization.
Also have producer to set about improving combustion rate from coal gas and Air mixing and carry out energy-conservationly, all these are that the energy-saving and cost-reducing of China contributes.Be further to improve capacity usage ratio, by a large amount of experimental developments a kind of more effectively cooking stove energy saver, energy consumption has further and reduces, if can obtain promoting, all benefits in the people with state.
Summary of the invention
