Abstract

This invention relates to a method of operating a regenerative furnace to capture a greater portion of its waste heat. A substantially greater amount of air than that required for combustion is passed through the air intake side of the regenerative furnace. The non-combustion clean hot air is taken from the furnace and conducted to an auxiliary heat-utilizing apparatus mounted exteriorly of the furnace.
