ABSTRACT:
A supporting structure for a blast furnace in which the mantle and stack are supported on columns spaced a substantial distance from the furnace. Trusses and girders span the spaces between columns. The girders carry a frame which surrounds the furnace above the mantle. Hangers are suspended from the frame and girders and connected to the mantle. The supporting structure has advantages that it allows more room for maintenance of the furnace, and that there is little likelihood of damage to the columns in the event of a burnout.
