    Abstract: In an improved system for recovering heat from a combustion gas produced by burning wastes, the combustion gas or combustible gas produced by partial burning of the wastes subjected to dust filtration in a temperature range of 450-650° C. at a filtration velocity of 1-5 cm/sec under a pressure of from −5 kPa (gage) to 5 MPa before heat recovery is effected. The dust filtration is preferably performed using a filter medium which may or may not support a denitration catalyst. Heat recovery is preferably effected using a steam superheater. The dust-free gas may partly or wholly be reburnt with or without an auxiliary fuel to a sufficiently high temperature to permit heat recovery. The combustion furnace may be a gasifying furnace which, in turn, may be combined with a melting furnace. If desired, the reburning to a higher temperature may be performed under pressure and the obtained hot combustion gas is supplied to a gas turbine to generate electricity, followed by introduction of the exhaust gas from the gas turbine into a steam superheater for further heat recovery. The system can raise the temperature of superheated steam to a sufficient level to enhance the efficiency of power generation without possibility of corrosion of heat transfer pipes by the combustion gas or combustible gas.

    Abstract: The combination of a vessel and a stopper assembly. The vessel has a wall defining a storage space for a supply of a flowable material and an orifice on the wall communicating through the body from the storage space to externally of the storage space. The stopper assembly selectively blocks the orifice. The stopper assembly has a frame, a stopper element with a blocking surface on the frame that is movable relative to the vessel between i) a closed position wherein the blocking surface substantially blocks the orifice and ii) an open position, and a repositioning mechanism for moving the stopper element relative to the vessel with the stopper element remaining in the closed position to thereby avoid fixing of the stopper element to the vessel.
