Under possess thermal radiation capability far above gas flame so that the radiant heat that the bottom of a pan obtains is significantly increased, improve tradition
Gas-cooker heat transfer type mainly based on convection heat transfer' heat-transfer by convection.
Full premix combustion stove need not in combustion supplement auxiliary air, therefore the stove that burns may be designed to close stove
Thorax, the chamber of a kitchen range is made using fire-resistant heat insulating material, and scribbles highly-reflective coating in inwall, heat is reflected to pan, while chamber of a kitchen range wall
Relatively low heat conductivility, substantially reduces radiation loss of the chamber of a kitchen range wall to environment, further increases the thermal efficiency of gas-cooker；Separately
The external closing type chamber of a kitchen range is additionally favorable for collecting, and there is certain remaining warm tail gas to carry out heat recovery.
In a word, porous media fully pre-mixing gas combustion stove is by the excellent heat-transfer character phase of full premix combustion technology and porous media
With reference to realizing that stable, efficient, energy-saving and environmental protection burning provides a new way for gas-cooker.
