Abstract

A catalyst for after market installation into unvented consumer kerosene heaters is provided. In a preferred embodiment plural stainless steel screens each coated with a catalyst material consisting of alumina and a metal from the platinum group or compound thereof is suspended within the kerosene heater. The peripheries of the screens are joined to one another so as to promote fast start up and slow cool down of the catalyst. The catalyst is coated directly on the steel wires of the screen, without intervening ceramic support structure, so as to reduce thermal mass and cost.
