Abstract
A hot air blower is provided having a first material, a second material, and a gap disposed between the two materials. The gap provides residence time in order for a gaseous flow delivered through the blower to become heated. The materials preferably comprise porous ceramic foam and provide a tortuous path for the gaseous flow. The preferred ratio of the volume of the materials to the volume of the gap is 3. The blower also preferably comprises a heating element for imparting heat to the gaseous flow, and a fan for creating the flow.
