ABSTRACT:
A thrust containment apparatus is disclosed for use with a pressurized rotary kiln gasifier. The thrust containment apparatus maintains stationary hoods mounted on both ends of the kiln shell in fixed positions by relieving the hoods of forces generated by high pressures within the kiln. The thrust containment device comprises braces mounted on the hoods on the sides remote from the kiln shell. Tie members, or tie rods, extending along the exterior of the kiln shell connect the braces. An expandable bellows is provided between one brace and its adjacent hood. As tie members deform through thermal and tensile expansion, the bellows accomodates the expansion while maintaining a gas-tight seal between the hood and the brace. Being of equal internal pressure as the kiln and having a diameter against the hood equal to the diameter of the seal connecting the hood to the kiln, the bellows relieves the hoods of all pressure forces and transmits these forces to the braces and tie rods thereby ensuring continuous stationary positioning of the hoods.
