System to achieve full combustion turbine load in HRSG limited combined cycle plants
A method of suppressing steam production in a HRSG where a volume of feed water is diverted upstream bypassing a portion of the economizer and returning the volume of diverted feed water to a downstream portion of the economizer. A control logic circuit is used to manipulate a suppression control valve regulating the bypassed feed water, thereby reducing the temperature of water in the steam drum. Bypassing feed water flow into a downstream portion of an economizer reduces the steam production rate in the steam drum by increasing the evaporator approach temperature, permitting gas turbines to operate at base load even after an upgrade, by preventing the waste heat boiler from exceeding its rated capacity and pressure.

An axle extends between the first cam support and the second cam support. A gripper is rotatably engaged to the axle between the first cam support and the second cam support. The gripper includes a first wall, a second wall, and a base extending between the first wall and the second wall, the base has an opening where the opening is positioned between and proximate to the forward edges. The opening receives a pin of a liner and insulation system where rotation of the handle in a forward direction applies leverage against the first cam support and the second cam support to bind the pin in the opening and compress the liner and insulation system immediately prior to welding.
The boiler cleaning apparatus and method provides for cleaning the exterior surfaces of a heat exchanger. The apparatus and method include tools and steps, respectively, for temporarily spreading tubes and holding open the tubes to gain access to tube lanes. Once access to a lane is attained, a nozzle assembly having an outlet for blowing high velocity cleaning fluid is selected from a group of nozzle assemblies. The selected nozzle assembly will have an outlet for blowing fluid in a direction that effectively cleans the tubes adjacent the opened lane. After the tubes are cleaned the tool for holding the lane opened is removed and the process is repeated for another lane.

Air cooling system and method for a heat recovery steam generator inlet
The air cooling system and method for a heat recovery steam generator (HRSG) inlet provides a combined cycle power plant utilizing a powerful fan coupled to ductwork connected to pipes that enter the HRSG inlet duct coupled to an exhaust duct of a Combustion Turbine (CT) for lowering the temperature of the CT exhaust gas provided to the heat recovery steam generator by the CT. The cool air injection system is utilized during low load operation or startup of the CT to ensure that spray water from an inter-stage desuperheater in an HRSG is fully evaporated prior to entering the downstream superheater or reheater. A feedback system includes temperature elements measuring the mix temperature that regulates the cooling air injection rate into the HRSG inlet.

The boiler cleaning apparatus and method provides for cleaning the exterior surfaces of a heat exchanger. The apparatus and method include tools and steps, respectively, for temporarily spreading tubes with a wedge and holding open the tubes with a block to form and gain access to tube lanes. Once access to a lane is attained, a nozzle assembly having an outlet for blowing high velocity cleaning fluid is selected from a group of nozzle assemblies. The selected nozzle assembly will have an outlet for blowing fluid in a direction that effectively cleans the tubes adjacent the opened lane. After the tubes are cleaned the tool for holding the lane opened is removed and the process is repeated for another lane.
An economizer for a heat recovery steam generator utilized to improve the efficiency of the Rankine cycle by preheating the water that flows to the evaporator section. The economizer multi-pass sections include up-flow tubes only. This arrangement greatly reduces thermal stresses on the tubes by ensuring that each individual tube in any fluid-flow pass operates at the same or similar temperature. The design of the invention does this by causing all tubes in any fluid-flow pass to have the same upwards fluid flow direction and similar fluid flow velocity. No unstable backflow (i.e. flow in the reverse direction) occurs in any of the tubes. Heated down-flow tube sections are totally eliminated in this design. Respective jumper pipes are provided to conduct the water from the top of an economizer panel to the bottom of an adjacent panel.
