Title: Vertical furnace for gasification of coal - with free expansion of replaceable inner lining
IPC: C10J3/48
Filed: 1982-07-16
Abstract: The shell of a vertical furnace for the gasification of coal has a lining resistant to high temperatures. Its domed top is supported by a primary insulating lining of strong bricks. Within is a sec. lining, of replaceable bricks, resistant to high temp. and erosion by slag, but not necessarily as strong as the primary. This lining extends vertically within the base of the dome, independent of it, and able to expand freely when hot, without vertical loading on it, or the dome. One or more layers of brick and insulating cement may be placed between primary lining and shell, and any spaces filled with paved insulation. The inner lining can expand freely, without tending to lift the dome, or to impose compressive stresses on the lining. The bricks can be easily replaced, without destroying the support for the dome, and they can be made in a material chosen for temp. resistance rather than strength.
