Abstract
The invention discloses a gas multi-orifice direct injection furnace end cover, which is suitable for a furnace end of a gas cooking appliance and is arranged above a furnace end body of the gas cooking appliance. The gas multi-orifice direct injection furnace end cover is provided with a plurality of gas orifices, wherein central axes of all the gas orifices are crossed with a central axis of the furnace end body at an included angle alpha, wherein the alpha is greater than 0 degree and less than or equal to 40 degrees; the number N of the gas orifices is greater than or equal to 80 and the diameters D of the gas orifices are less than or equal to 3mm, so that gases injected through the gas orifices can generate a greater pressure against burning gases below the gas cooking appliance; and meanwhile, the gases are sufficiently mixed with air, in this way, the burning gases are higher in temperature and the gas cooking appliance absorbs more heat, therefore, the energy saving effect of the gas cooking appliance is realized.
Description
Technical field
The present invention relates to the gas kitchen ranges burner, be specifically related to a kind of porous that is applied to gas kitchen ranges and directly spray stove top.
Background technology
The form of the stove top of existing gas kitchen ranges is varied; Combustion gas also has nothing in common with each other from the direction that the spray orifice of stove top ejects; But all there is a common defective; Be that main burner is not that whole fuel gas injection directions face toward the burner central axial direction, the injection direction that has all or part of gas jet orifice can decomposite the direction that departs from the burner central axis.As: two kinds of common on the market gas kitchen ranges stove tops, a kind of is the burner of combustion gas cyclone-type gas kitchen ranges, it is the tangential direction on the face of cylinder at center that the injection direction of its combustion gas can decomposite with the burner central axis; Another kind is the burner of combustion gas direct-injection gas kitchen ranges, and it is the normal direction on the face of cylinder at center that the injection direction of its combustion gas can partly decomposite with the burner central axis.Those combustion gas that depart from burner central axial direction ejection of gas kitchen ranges reduced relatively combustion gas to cooker at the bottom of the pressure of burning gases, make that the temperature of burning gases reduces relatively at the bottom of the cooker, the heat energy that cooker is absorbed reduces relatively.
Summary of the invention
Technical problem to be solved by this invention is: to the deficiency of above-mentioned prior art, provide a kind of combustion gas porous that is applied on the gas kitchen ranges and has an energy-saving effect directly to spray stove top.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of combustion gas porous is directly sprayed stove top; It is installed in the furnace end body top of gas kitchen ranges; And this stove top is provided with several gas jet orifices, is characterized in: the central axis of said gas jet orifice and the central axis of furnace end body intersect and the α that has angle, 0 °＜α≤40 °.
The number N of above-mentioned gas jet orifice>=80, the aperture D≤3mm of above-mentioned gas jet orifice can make combustion gas fully mix with air, and combustion gas is fully burnt.Above-mentioned stove top also can be one-body molded with this furnace end body.
By physical Charles' law: certain gas of certain mass, under the situation of constancy of volume, pressure P is directly proportional with thermodynamic temperature T, is shown with formula table: P=CT, C are proportionality constants; Avogadros constant: molecule (particulate) number that contains in 1 mole of any material is identical, uses N
A=6.02 * 10
23Mol
-1And the pressure of mechanical parameter gas is numerically equal to the scientific laws such as sweay of the gas molecule that receives on the unit are in the unit interval, and we can release, when gas volume V one regularly, pressure P is big more, then the product MT of mass M and temperature T is big more.The burning gases of gas kitchen ranges mainly are to contact exchange with the heat exchange of cooker; There is such rule before and after the heat energy Q of its heat exchange, the mass M of gas, heat exchange between the intrinsic specific heat capacity C of the temperature difference △ T of gas and gaseous matter: Q=CM △ T; In sum; Can infer: the pressure of cooker surface burning gases is big more, and the heat energy that cooker absorbs is big more.
The present invention is used in several gas jet orifices is set on the stove top, and the central axis that makes gas jet orifice tilts to the central axial direction of furnace end body, and intersects and the α that has angle 0 °＜α≤40 ° with the central axis of furnace end body.And number N>=80 of gas jet orifice are set, aperture D≤3mm, so; Can know that by top scientific law of the present inventionly be arranged so that combusted gas generant pressure increases at the bottom of combustion gas from gas jet orifice ejection is to cooker, combustion gas fully mixes with air; Make fuel gas buring more abundant; The heat energy that cooker absorbs is more, thereby improves the thermal efficiency of gas kitchen ranges, and the content of carbon monoxide in the combustion gas dry flue gas of gas kitchen ranges is effectively controlled.
With concrete data the present invention is described further below.
Carry out the comparison and detection of air consumption with stove top of the present invention and existing ten thousand tame happy original-pack stove tops.
Key instrument equipment: electronic balance, gas flowmeter, thermometer, 26cm aluminum pot, ten thousand tame happy board economical gas kitchen ranges (model JZT-QE2B), carbon-monoxide analyzer etc.
Content with reference to carbon monoxide in GB16410-2007 " household gas utensils national standard " the test thermal efficiency and the dry flue gas.During test, because the precision of test instrument is hanged down the big situation of testing result error that causes, the whole temperature of the water of test is increased to 90 ℃ in order to reduce, and the test water yield is enlarged to 4kg.During test, 8 ℃ of environment temperatures, aluminum pot diameter 26cm adds water 4kg in the aluminum pot, and the combustion gas of using is natural gas 12T.Test result is following:
Use the original-pack stove top of ten thousand tame happy boards, water temperature rises to 90 ℃ from 8 ℃, and the secondary air consumption is respectively 86 liters and 85 liters, and average air consumption is 85.5 liters.
Use stove top of the present invention, water temperature rises to 90 ℃ from 8 ℃, and the secondary air consumption is respectively 74 liters and 73 liters, and average air consumption is 73.5 liters, and records that carbon monoxide content is 0.023% in the gas kitchen ranges dry flue gas.
Solar term rate: (85.5-73.5) ÷ 85.5=14%;
The thermal efficiency improves relatively: (85.5-73.5) ÷ 73.5=16.3%;
Can know from top data, use stove top of the present invention, improve more than 10% relatively, have more energy-saving effect than the thermal efficiency of the stove top of the economical gas kitchen range that use prior art, and in the dry flue gas of gas kitchen ranges the content of carbon monoxide less than 0.025%.
