Description
Technical field
The utility model belongs to cooking appliance design and manufacturing technology field, especially belongs to monoblock type gas kitchen ranges design neck
Domain, more particularly to a kind of combined type catalytic burner.
Background technology
China's natural gas consumption figure is huge, and only China's natural gas consumption figure in 2012 just reaches 150,000,000,000 Nm3 according to statistics, and
Consumption figure increases year by year.Methane is the key component of natural gas, is a kind of clean energy resource.Because methane molecule is highly stable, very
Difficulty is activated, and traditional flame combustion has substantial portion of energy to be discharged in the form of visible ray, and capacity usage ratio is very low；Simultaneously
Because the temperature of flame combustion is high, the N2 in air participates in reaction and forms oxynitrides, causes environmental pollution.And use catalysis
Combustion system, methane not only high conversion rate, capacity usage ratio is high, can also substantially reduce the temperature of course of reaction, avoid nitrogen oxygen
The generation of compound.But catalyst coat heat endurance used in the catalytic burner generally existing used at present is poor, easy
The problems such as vapor and element sulphur are poisoned, coating is easy to fall off, gas-cooker unreasonable structure is, it is necessary to further improve catalysis burner plate
Performance.China's main flow is commercial at present and household gas range uses open, blowing-type combustion system more.However, open combustion
During burning, combustion gas and air can not be mixed in advance in the burner, but mixed on burner surface side and become burning, shape
Into flaming combustion, combustion heat energy only has less part to pass to heated vessel, and other most of heat energy are in flame flowing
It is emitted in environment.In addition, in open combustion process, the imperfect combustion situation of Some gases also be present, not only cause to dive
In hot loss of energy, while cause in its flue gas containing harmful substances such as more carbon monoxide and oxynitrides.
And existing infrared ray non-flaming combustion stove, premix in gaseous mixture inadequate, can not be uniformly distributed in premix chamber,
So cause insufficient, the firepower skewness that burns, when and there is the shortcomings of sudden strain of a muscle emits naked light flare, it is necessary to further improve and carry
High thermal efficiency.
