Abstract
A heater having a planar 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. A source of fuel and air is then supplied to the first side of the metal sheet resulting in catalytic combustion which heats the metal sheet. The metal sheet can serve as a cooking stove.
Claims17
A heater comprising:
- a metal sheet having a first and second surfaces,
- a porous metal oxide layer formed directly on said first surface of said metal sheet,
- a combustion catalyst impregnated within said porous metal oxide layer, the catalyst effecting flameless catalytic combustion,
- a source of fuel, and
- a chamber which the first surface faces,
- wherein fuel interacts with the catalyst in the porous metal oxide layer and undergoes flameless catalytic combustion which generates heat,
- wherein the second surface is an exterior surface where cooking takes places and heat generated by the flameless catalytic combustion at the first surface of the sheet is conductively transferred through the metal sheet to the second surface raising the temperature of the second surface to a temperature suitable for cooking food.
