A new technical approach is necessary to increase not only energy efficiency, productivity and product quality but also reduction of NOx formation in industrial processes. The aim of the study was to develope an energy efficient industrial gas burner which meet the above requirements. The works were concentrated on the surface combustion using a metallic fiber mat as a burner material. The first year studies included fabrication method and combustion tests for low/high load gas burner. A relatively low NOx, stable combustion and uniform surface radiation characteristics were confirmed. (author). refs., figs., tabs.
