Abstract
A method of heating up to working temperature from cold, a furnace of the regenerative or recuperative type having its interior lined with refractory material, which method comprises projecting into the furnace from one or more substantially non-radiant high velocity burners a flow of hot gases, causing said gases to circulate around said interior to heat same substantially uniformly, introducing to said interior air (preferably from the normal firing system of the furnace) alternately via one and then the other of the regenerators, and controlling said burner or burners to cause it or them to pass to an excess fuel condition by which said air is consumed within the furnace, thereby pre-heating the furnace and the regenerators up to full working temperature.
