Abstract

Recuperative furnaces, such as soaking pits, have recuperators formed of sets of ceramic tiles arranged end to end with aligned holes in each set of tiles forming one series of passages for the flue gas and openings between the sets of tiles forming a second series of passages for the air to be heated. The heated air from the recuperator is directed through an air tunnel to an entry or burner port where it is mixed with coke oven gas or other fuel. Combustion is completed in the combustion or heating chamber which also receives the ingots to be heated. The burnt gases pass from the chamber through a flue gas port to the recuperator. It is impossible to maintain a gas tight connection between the tile. To prevent air leakage into the flue gas passages and increase fuel efficiency and production the entry port area is made at least approximately 75 percent (preferably 100 percent) of the cross sectional area of the air tunnel and the flue port area is made at least approximately 75 percent (preferably 100 percent) of the total cross sectional area of the flue gas passages in the recuperator.
