Abstract
The utility model relates to a porous ceramic wafer for a gas range, which is produced by cordierite and other hard ceramic material. The utility model is characterized in that the cross-section of a fire hole forms a hexagon, which can achieve the small area of a single fire hole and the appropriate open area through technology manufacture, efficaciously overcomes the phenomenon of tempering and makes combustion completely for a manufactured gas infrared gas stove, and enhances the thermal performance of the gas range.
Description
The utility model relates to the improvement of gas stove burner, especially to the improvement of porous ceramics piece in the household infrared ray kitchen range of artificial coal gas.
As everyone knows, since the household infrared ray gas kitchen ranges appears on the market, now accepted by consumers in general.Compare with the air suspended type kitchen range, it have energy-conservation, efficient, pollute less, advantage such as security performance is good, health is clean.Because infrared burner adopts a premix air burning mode, burning is carried out on its red-hot surface, porous ceramics piece surface temperature height, and burning velocity is fast, easily causes tempering phenomenon.When being mounted with when infrared radiation produced the utensil of strong reflection the easier generation of tempering phenomenon on the kitchen range.Especially when the source of the gas that uses during as artificial coal gas, generally all calorific value is low owing to artificial coal gas, and burning velocity is fast, and therefore, the tempering problem that solves the artificial coal gas infrared kitchen range becomes a big technical barrier of this gas kitchen ranges.
Solve the tempering phenomenon of infrared gas stove tool, following several method is generally arranged: (1) reduces primary air ratio, reduces total fire hole area, if but primary air reduces too much, causing incomplete combustion, and the carbon monoxide content in the flue gas is raise, then is worthless; (2) increase the distance in the combustion front and the bottom of a pan, this method will make the thermal efficiency reduce greatly, thereby also is worthless; (3) reduce each fire hole area, this is the better method of dealing with problems.But reduce the restriction that each fire hole area is subjected to process for making, want the fire hole area that reaches required, square fire hole and garden shape fire hole are to be difficult to meet the requirements of.
The purpose of this utility model is by changing the shape of each fire hole, appropriate in the hope of the fire hole percent opening of producing on the technology, and the porous ceramics piece that each fire hole area is little, reach under the prerequisite that does not reduce the thermal efficiency, can overcome tempering phenomenon, the carbon monoxide content in the combustion product gases is not raise.
The utility model is realized as follows: the porous ceramics piece gross area is constant, and the cross section of each fire hole (1) becomes regular hexagon by original square hole shape or garden hole shape, and each regular hexagon fire hole area is not more than 1 square millimeter.In kitchen range are produced, can specifically determine each fire hole area according to the kind and the component of various places combustion gas, if artificial coal gas, each fire hole area then should be not more than 0.8 square millimeter.Because extrusion process, regular hexagon fire hole (1) distributes by rounded projections arranged.Adopted the hexagon fire hole, compared with square fire hole, the hole wall thickening, the centre-to-centre spacing of fire hole has strengthened, and particularly for the situation of small fire hole, percent opening has also reduced.And the porous ceramics piece of regular hexagon fire hole (1) is compared with garden hole shape potsherd, and hole count is more, and hole wall is thinner, and percent opening is higher.When single fire hole area was not more than 0.8 square millimeter, garden hole shape potsherd, maximum percent opening were 28.5%, the smallest aperture rate 44% of square hole shape potsherd, and the percent opening of regular hexagon fire hole potsherd can be in the 30%-40% scope.For the infrared gas stove tool, need appropriate primary air and fire hole area, adopting the porous ceramics piece of regular hexagon fire hole can be that total fire hole area is regulated primary air by percent opening just, makes it reach appropriate primary air ratio 1≤α≤1.3.Reach simultaneously and adopt corresponding fire hole size, overcome tempering phenomenon effectively, and the carbon monoxide content in the flue gas is not raise, the thermal efficiency does not reduce.In order to guarantee service life, potsherd should adopt hard ceramic material.
Advantage of the present utility model is calorific value low, and burning velocity is fast, and easily the artificial coal gas of tempering can more effectively overcome tempering phenomenon, and the carbon monoxide content in the flue gas is controlled in the very low scope, satisfies the requirement of standard, and thermal efficiency height.
Below in conjunction with the description of the drawings, provide embodiment.
Fig. 1 is a longitudinal sectional view of the present utility model;
Fig. 2 is local fire hole lateral cross section of the present utility model and distribution map thereof.
Embodiment 1:
A kind of porous ceramics piece that uses artificial gas appliance is made with the cordierite raw material, and the cross section of its each fire hole 1 is a regular hexagon, and distribution triangular in shape on potsherd.
