A Partial Conversion Of A Gas-Air-Fired Television Furnace To Oxy-Fuel Combustion

Oxy-fuel became an attractive alternative to extend the furnace life of a tv furnace that was experiencing severe plugging and collapsing of the checkers. The on-the-fly conversion was made by inserting oxy-fuel burners directly into the breastwalls and replacing the energy in the affected ports with oxy-fuel combustion. An additional advantage to the conversion was a substantial reduction in NOx. The NOx reduction was accomplished with only a portion of the furnace being fired on oxy-fuel burners. This paper will describe the conversion and review the results of the conversion.
