Abstract
The invention relates to a burning plate formed by mixing mullite and cordierite. The burning plate comprises a mullite part and a cordierite part. The mullite part is connected with the cordierite part to form the burning plate. The weight percentage of the mullite part and the cordierite part is 20%-80%:80%-20%. According to the burning plate, the feature of low coefficient of thermal expansion of the cordierite and the feature of high mechanical strength of the mullite are fully utilized, and the coefficient of thermal expansion of the cordierite is slightly higher than that of the cordierite, so that the coefficient of thermal expansion of the burning plate made of the composite material formed by the mullite and the cordierite is not increased greatly, the mechanical strength is improved obviously, and thus the service life of the burning plate can be prolonged greatly.
Description
Technical field
The present invention relates to a kind of burner plate, refer to a kind of burner plate utilizing the composite of mullite and cordierite to make especially.
Background technology
As everyone knows, ceramic wafer Gas-fired Radiator in Municipal, since the forties in 20th century comes out, has been used in heating and baked goods field in civilian.The operation principle of Infrared Gas Range with Ceramic Plaque is: combustion gas utilizes the whole air capacity combustion gas required for the burning of injector pre-mixing gas combustion, air mixture burns from the thousands of aperture track overflow of ceramic wafer with the speed of 0.1-0.14m/s, plate face is heated to crimson state, temperature reaches 800-900 degree, plate face and high-temperature flue gas carry out radiation and Convective Heating to pot, and now fuel gas buring is nonflame state.And the operation principle of atmospheric gas stove is: combustion gas utilizes the portion of air amount of injector only required for premixed combustion, then with the speed of 1.0 ~ 3.5m/s, some fire holes through head flow out, and obtain auxiliary air again from surrounding and burn, form the flame of originally lighting a fire with inside and outside flame, the high-temperature flue gas of generation mainly heats pot in the mode of heat convection.
Infrared Gas Range with Ceramic Plaque is compared with atmospheric gas stove, and its thermal efficiency is high, and energy-saving effect is remarkable.Infrared Gas Range with Ceramic Plaque has ceramic wafer radiant body.Ceramic wafer heats by a part of heat of fuel gas buring, and ceramic wafer is heated pot by radiation again.This is the main cause that the Infrared Gas Range with Ceramic Plaque thermal efficiency is higher.Infrared Gas Range with Ceramic Plaque adopts full premixed combustion, and excess air is few, and theoretical temperature combustion is high, and flue gas loss is little, and heat exchange amount is increased, and the thermal efficiency improves.Infrared Gas Range with Ceramic Plaque adopts lower pan bracket height, increases heat exchange, reduces radiation heat loss, thus improves the thermal efficiency.Just because of above-mentioned reason so present infrared ceramic porcelain plate is applied in kitchen range very widely,
Present infrared ray porous ceramic plate mainly utilize at present cordierite mix with metal material after make, the thermal coefficient of expansion of cordierite is low, and the infrared ray porous ceramic plate utilizing cordierite to make for raw material has extraordinary heat endurance in the process of heating, its product is not easy cracking, long service life.
But the mechanical strength of cordierite is not high, the infrared ray porous ceramic plate utilizing cordierite to make for raw material often can because stressedly exceed strength that cordierite itself can bear and damage producing, in transport and process used in everyday.
Mullite has good mechanical strength, but its thermal coefficient of expansion is higher than cordierite, if be used alone mullite to make infrared ray porous ceramic plate, then because of the problem that mullite thermal coefficient of expansion is high, result in its product, to there is heat endurance bad, the problem that service life is short.
If adopt the composite of mullite and cordierite to make burner plate, then can play cordierite thermal coefficient of expansion low simultaneously, the feature that mullite mechanical strength is high, thermal coefficient of expansion due to mullite is a little higher than cordierite, so its thermal coefficient of expansion of burner plate adopting the composite of mullite and cordierite to make can't promote very large, and mechanical strength is really significantly improved, thus greatly can promote the service life of burner plate, but also do not occur utilizing the composite of mullite and cordierite to make the technology of burner plate now, and this is the major defect for conventional art.
Summary of the invention
The invention provides the burner plate that a kind of mullite and cordierite mix, its thermal coefficient of expansion of burner plate adopting the composite of mullite and cordierite to make can't promote very large, and mechanical strength is really significantly improved, thus greatly can promote the service life of burner plate, and this is main purpose of the present invention.
