Rare earth oxide materials previously identified to produce highly selective radiant emissions when used in ceramic mantles have been incorporated into large porous surface radiant burner structures. Results to date have been promising, as spectral selectivity has been demonstrated using ytterbia fibers cast over a porous matrix of more conventional ceramic fibers. Concept feasibility was demonstrated during the first year and improved durability is currently being investigated. High emissivity materials are being added to broad band radiant burners to increase radiant flux and improve thermal efficiency of radiant burners.
