Abstract
A kind of gas multi-orifice direct injection furnace end cover, burner suitable for gas cooker, it is installed in above the furnace end body of gas furnace, the stove top is equipped with several gas jet orifices, the central axis of the whole gas jet orifice intersects with the central axis of furnace end body and the α that has angle, 0o ＜ α≤40o, and number N >=80 of the gas jet orifice, bore dia D≤3mm, so that the combustion gas sprayed in the air from gas injection increases combusted gas generant pressure under cooker, combustion gas simultaneously is sufficiently mixed with air, so that the temperature higher of burning gases, cooker absorbs heat bigger, to realize the energy-saving effect of gas cooker.
Description
Technical field
The present invention relates to gas combustion stove burners, and in particular to a kind of multi-orifice direct injection furnace end cover applied to gas cooker.
Background technology
The form of the stove top of existing gas cooker is varied, and combustion gas is also each from the direction that the spray orifice of stove top ejects
It differs, but all there is a common defect, is i.e. main burner is not all of fuel gas injection direction against burner central axis
Direction, there are the directions that the injection direction decomposable asymmetric choice net of all or part of gas jet orifice goes out to deviate burner central axis.Those are partially
The combustion gas that burner central axial direction from gas cooker sprays relatively reduces combustion gas to the pressure of cooker bottom burning gases, makes
The temperature relative reduction for obtaining cooker bottom burning gases makes the thermal energy that cooker absorbs is opposite to reduce.
Invention content
The technical problem to be solved by the present invention is to：In view of the above shortcomings of the prior art, it provides a kind of applied to combustion gas
On kitchen range and with energy-saving effect gas multi-orifice direct injection furnace end cover.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of gas multi-orifice direct injection furnace end cover,
It is installed in above the furnace end body of gas cooker, and the stove top is equipped with several gas jet orifices, its main feature is that：The gas injection
The central axis in hole intersects with the central axis of furnace end body and the α that has angle, 0o ＜ α≤40o.
Number N >=80 of above-mentioned gas jet orifice, aperture D≤3mm of above-mentioned gas jet orifice can make combustion gas fully mixed with air
It closes, and combustion gas is made fully to burn.Above-mentioned stove top can also be with the burner body by integral forming.
By the Charles' law of physics：Certain gas of certain mass, in the case of constancy of volume, pressure P and heating power
It is directly proportional to learn temperature T, is expressed as with formula：P=CT, C are proportionality constants；By Avogadro constant（Contain in any substances of 1mol
Some molecular numbers are identical, use NA=6.02×1023mol）And the pressure of mechanical parameter gas was numerically equal in the unit interval
The sweay for the gas molecule being subject on unit area, we can release, and when mono- timings of gas volume V, pressure P is bigger, then matter
The product for measuring M and temperature T is bigger.The burning gases of gas cooker mainly contact exchange with the heat exchange of cooker, and heat is handed over
Before and after the mass M of the thermal energy Q, gas that change, heat exchange the temperature difference Δ T of the gas and intrinsic specific heat capacity C of gaseous matter it
Between there are such rules：Q=C M Δ T, in conclusion can be inferred that：The pressure of cooker surface burning gases is got over
Greatly, the thermal energy that cooker absorbs is bigger.
The present invention, which is used on stove top, is arranged several gas jet orifices, and makes the central axis of gas jet orifice to furnace end body
Central axial direction tilts, and intersects with the central axis of furnace end body and the α that has angle, 0o ＜ α≤40o.And gas injection is set
Number N >=80 in hole, aperture D≤3mm, in this way, by scientific law above it is found that the setting of the present invention makes from gas jet orifice
The combustion gas of ejection increases the combusted gas generant pressure in cooker bottom, and combustion gas is sufficiently mixed with air, keeps fuel gas buring more abundant,
Cooker absorb thermal energy it is more, to improve the thermal efficiency of gas cooker, at the same can also make in the dry flue gas of gas cooker one
The content of carbonoxide is effectively controlled.
With specific data, the invention will be further described below.
The contrasting detection of air consumption is carried out with existing ten thousand happy original-pack stove tops with the stove top of the present invention.
Key instrument equipment：Electronic balance, gas flowmeter, thermometer, 26cm aluminum pots, ten thousand happy board energy saving gas burners
(model JZT-QE2B), carbon-monoxide analyzer etc..
With reference to GB16410-2007《Household gas utensils national standard》Test carbon monoxide in the thermal efficiency and dry flue gas
Content.When test, to reduce the big situation of testing result error, the water final temperature of test caused by the precision of test instrument is low
It improves to 90oC, test water is enlarged to 4kg.When test, environment temperature 8oC, aluminum pot diameter 26cm, aluminum pot is interior to add water 4kg, makes
Combustion gas is natural gas 12T.Test result is as follows.
Using ten thousand happy original-pack stove tops of board, water temperature rises to 90oC from 8oC, and secondary air consumption is respectively 86 liters and 85 liters,
Average air consumption is 85. 5 liters.
Using the stove top of the present invention, water temperature rises to 90oC from 8oC, and secondary air consumption is respectively 74 liters and 73 liters, is averaged
Air consumption is 73. 5 liters, and it is 0.023% to measure carbon monoxide content in gas cooker dry flue gas.
Solar term rate：(85.5-73.5) ÷85.5 =14% .
The thermal efficiency is opposite to be improved：(85. 5-73. 5) ÷73. 5=16. 3% .
From upper face data it is found that using stove top of the invention, the stove of the energy-saving gas cooking range than using the prior art
The thermal efficiency of skull opposite will improve 10% or more, more energy-saving effect, and carbon monoxide contains in the dry flue gas of gas cooker
Amount is less than 0.025%.
