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 said one side of said actuator piston to permit the manifold piston to move in the opposite direction as the temperature of the effluent gas decreases below the predetermined temperature thereby closing additional spray nozzles and permitting the temperature of the effluent gas to rise.
