Abstract: A purge drain valve including a spool spliced in a fluid line includes a control valve and an actuator coupled to the control valve for regulating fluid flow. During a washing operation, fluid flows between a supply end and a delivery end of the spool, and during a purging operation, the control valve diverts fluid entering the supply end from the delivery end towards a drain leg. A washing system includes a fluid supply coupled to an input of a wash delivery system and a delivery line coupled to an output of the wash delivery system. The purge drain may be spliced into the delivery line to permit fluid to reach a wash apparatus during a washing operation and to prevent fluid from reaching the wash apparatus during a purging operation. A rinse cycle sensor apparatus may be employed to indicate to an operator if a washing operation is complete based upon a conductivity of fluid exiting from a device being washed.

Abstract: A combustor for a gas turbine is provided having a nozzle assembly located at one end and a combustion chamber defining a second end of the combustor. A venturi is positioned within the combustor, between the nozzle and the combustion chamber. The venturi defines a passageway therein having a first side facing the nozzle and a second side facing the combustion chamber. Compressed air is directed into an inlet in fluid communication with the first and second sides of the venturi passageway. The venturi passageway directs the compressed air from the inlet in opposite directions within the first and second sides of the passageway for cooling the venturi.

Abstract: A secondary nozzle is provided for a gas turbine. The secondary nozzle includes a flange and an elongated nozzle body extending from the flange. At least one premix fuel injector is spaced radially from the nozzle body and extends from the flange generally parallel to the nozzle body. At least one second nozzle tube is fluidly connected to the fuel source and spaced radially outward from the first nozzle tube with a proximal end fixed to the flange. The second nozzle tube has a distal end, spaced from the proximal end, with at least one aperture therein. A passageway extends between the proximal end and the distal end of the second nozzle tube, with the passageway fluidly connecting to the fuel source and the aperture.

Abstract: A combustor for a gas turbine is provided having a nozzle assembly located at one end and a combustion chamber defining a second end of the combustor. A venturi is positioned within the combustor, between the nozzle and the combustion chamber.

Abstract: A system for cleaning gas turbine engines is described. More specifically, methods and apparatuses for cleaning stationary gas turbines and on-wing turbofan engines found on aircraft are disclosed that includes a trailer-mounted, automated low-pressure water delivery system, additive and detergent injection system, nozzle and manifold technology, and active waste water effluent collector system.

Abstract: A fluid delivery skid with a pre-fill system for supplying fluid has one or more stages including a first valve and a second valve, each having an open and closed position. The stages have active and inactive states to provide a desired flow rate of fluid to an apparatus for distribution of the fluid. In an active state, fluid is received in the stage and pressurized with the first valve open and the second valve closed. Further, in an active state, fluid is released with the first valve closed and the second open. In an inactive state, at least the second valve is closed. A control unit is connected to a pump unit and controls operation of the pump to regulate the stages to supply pressure at a level determined to achieve the desired flow rate.

Abstract: A nozzle assembly for cleaning turbines includes an offline cleaning nozzle and a pair of online cleaning nozzles. The offline cleaning nozzle directs cleaning fluid towards the inlet of turbine. The online cleaning nozzles direct a cleaning fluid in a fan-shaped pattern in a direction substantially parallel to the direction of air flow within the turbine's inlet air duct, and intersecting with each other. The longest dimension of the fan-shaped spray pattern is substantially parallel to the direction of air flow within the duct.
