Abstract
A heater or article of cookware is formed of a metal sheet with a first and second surface. A metal oxide layer is formed on the first surface of the sheet and a combustion catalyst is impregnated into the metal oxide layer. Fuel and air is then supplied to the first side of the metal sheet resulting in flameless catalytic combustion which heats the metal sheet.
Claims20
A cookware article comprising:
- a metal piece having a first and second surfaces;
- a porous metal oxide layer formed directly on said first surface of said metal piece;
- and
- a combustion catalyst impregnated within said porous metal oxide layer, the catalyst effecting flameless catalytic combustion,
- wherein fuel interacts with the catalyst in the porous metal oxide layer and undergoes flameless catalytic combustion which generates heat, and heat generated by the flameless catalytic combustion at the first surface of the piece is conductively transferred through the metal piece to the second surface raising the temperature of the second surface.
