Abstract: A process for reducing the formation of dioxins in the incineration of wastes that includes using sodium carbonate or sodium bicarbonate to react with chlorides formed in the incineration process. When sodium bicarbonate is used in the temperature range of 1561.degree. F. to 518.degree. F. a greater porosity is achieved that achieves a high degree of removal of the chlorides thereby preventing their reaction to produce dioxins.

Abstract: An evaporative spray cooling system for cooling an effluent gas is disclosed including a pressurized supply of coolant fluid, a hydraulic cylinder manifold having a movable piston, individual spray nozzles communicating with ports spaced apart along the length of the hydraulic cylinder manifold, a hydraulic cylinder actuator having a movable piston operatively connected to the piston of the hydraulic cylinder manifold, said pressurized fluid supply communicating with one end of said hydraulic cylinder manifold to supply coolant fluid to the manifold, valve means for selectively supplying the pressurized fluid to one side of the hydraulic cylinder actuator piston for overcoming the supply fluid force on the hydraulic cylinder manifold piston to move the manifold piston in first one direction in response to an increase in effluent gas temperature above a predetermined temperature thereby opening more spray nozzles to decrease the temperature of the effluent gas and decreasing the pressure of the supply fluid on

Abstract: A refuse disposal system is disclosed including a combustion chamber, means disposed in the combustion chamber for supporting refuse to be burned, means for charging refuse on the support means, overfire means for supplying an increasing flow of combustion air above the support means as the temperature of the gaseous products of combustion increases above a first predetermined temperature, underfire means for supplying a decreasing flow of combustion air under the support means as the temperature of the gaseous products of combustion increases above the first predetermined temperature, override means for overriding the underfire means to decrease the flow of air under the support means when the temperature of the products of combustion decreases below a second lower predetermined temperature and means for reducing the rate with which the charging means places refuse on the support means when the temperature of the gaseous products of combustion increases above the first predetermined temperature.
