Abstract.
A radiant burner screen comprises a substrate formed by a heat resistant, porous, rigid, ceramic foam material having a thin tracery or reticular form demarcating the pores which open one into another and of which there are about 30 pores or less per 645.16 square millimeters. This ceramic foam material can be readily and easily permeated by hot gaseous products of combustion from a fluid fuel, for example natural gas, burner. The ceramic foam material which may be a silicate of alumina with preferably no free silica, bears a sprayed on radiation emitter coating at side of the screen. The emitter coating comprises a rare earth element and/or a compound of a rare earth. The rare earth may be ytterbium or erbium and the compound may be ytterbia or erbia. Heat from the hot products of combustion causes the emitter coating to emit radiation incident on a photovoltaic cell arrangement to produce electrical power therein output on line.
