Hot air ladle preheat station.

摘要

The hot air ladle preheat station (10) comprises an outer casing (16) defining an opening (70) for receiving a separately supported ladle (12) to be preheated. The opening (70) is dimensioned so wide as to form a dilution air space (72) about the ladle exterior. A wall (18) is spaced inward to the outer casing (16) and defines a space (74) therebetween having a lower section (30) for accommodating the ladle in spaced apart relationship from it and an upper flue section (28) connected via a recuperator (20) to a stack (22). A burner (32) is associated with the wall (18) in the lower section (30) for directing a flame (68) into the ladle (12) substantially coaxially thereto. Products of combustion are directed into the ladle (12) and exit from the ladle interior (64) into the space (74) formed with the wall (18). The products of combustion mix with and are cooled by the outside air entering through the dilution air space (72) and the mixture thus formed passes through the upper flue section (28) and through the recuperator (20) in heat exchange relationship with combustion sustaining gas utilized in the burner (30).
