Description
Technical field
The present invention relates to energy-saving kitchen range, and in particular to a kind of burner and gas-cooker.
Background technology
During fuel gas buring, the chemical reaction velocity of fuel gas buring is significantly larger than between combustion gas molecule and oxygen molecule
The speed of phase counterdiffusion mixing, therefore, restricts mixed process of the principal element of burning velocity raising between combustion gas and air.
If the mixing intensity between air-gas can be improved, it will burning velocity is greatly improved.But there is combustion in existing kitchen range
The problems such as gas is short with air mixture time, and combustion gas mixes uneven with air, so has substantial amounts of combustion gas not all to be ignited,
Cause to burn insufficient, imperfect combustion gas can produce black smoke, and burned flame heat is little, and spent combustion gas is more, burn
Water and the time lengthening of cooking, for this upper shortcoming, it is necessary to make improvements.
