An improved waste feed arrangement for feeding waste into a rotary combustor including a stepped support frame and a ram which pushes the waste through a doorway into the rotary combustor, the ram slidably engaging an upper step of the support frame and has a bracket on the outboard end to which a cam follower is rotatably attached, the cam follower rolls on a lower step of the support frame and a hydraulic cylinder is connected between the bracket on the ram and a bracket disposed in the support frame in such a manner that the hydraulic cylinders piston rod pushes the ram away from the doorway as it extends from the hydraulic cylinder providing a smaller, totally covered hydraulic cylinder and piston rod and an improved waste feed system.

Waste feed arrangement

A device for supplying feedwater to, and conveying feedwater from, a shaft tube assembly (20,22) of a machine having a rotary part, which assembly (20,22) has a longitudinal axis about which the assembly (20,22) rotates together with the rotary part, the device being composed of a housing which includes a cylindrical casing (2) having a cylindrical passage extending between its axial ends and a lateral feedwater passage (6) communicating with the cylindrical passage, a conduit member (8) having a second feedwater passage (10) and coupled to one axial end of the casing (2) to form a sealed joint with the casing (2), the conduit member (8) being positioned relative to the casing (2) such that the second feedwater passage (10) communicates with the cylindrical passage, and a closing member (12) coupled to the second axial end of the casing (2) to form a sealed joint with the casing (2), the closing member (12) having a circular opening coaxial with the cylindrical passage of the casing (2 ), the housing being constructed to receive the shaft tube assembly (20,22) such that the shaft tube assembly (20,22) extends through the circular opening of the closing member (12) and into the cylindrical passage of the casing (2) so that each feedwater passage (6,10) communicates with a respective one of a feedwater inlet (46) and feedwater outlet (48) of the assembly (20,22).

Rotary joint for conveying feedwater

A rotary combustor includes a rotatable cylindrical drum having axial seals extending from the outer periphery of the drum, and sealing structures for forming passages for providing combustion fluids along portions of the rotatable cylindrical drum. Each sealing structure includes a movable shoe positioned along the periphery of a portion of the rotatable cylindrical drum, a support positioned at a predetermined distance from the axial seals along a portion of the periphery of the rotatable cylindrical drum, and first and second spring units coupled between the support and the movable shoe. The spring units urge the movable shoe into contact with at least one of the axial seals. As a result, an air seal is continuously provided between the axial seal and the movable shoe even though the rotary combustor expands and contracts with temperature.
