For normal operation of the actuator, an operation cycle includes at least a proportional valve for switching to different operational conditions of the actuator and related engine components. The proportional valve is arranged in a supply line of pressurized liquid/gas and in a drain line connected to a tank, and control means for operation control and supervising functions. An emergency cycle is attached to the operation cycle of the actuator which is provided with: at least one solenoid valve for initiating an emergency operation impulse in case of detected failures; a plurality of pneumatically/hydraulically operated switch valves which may be activated through said impulse of an emergency signal from said solenoid valve; and whereby the emergency cycle is adapted to bypass said proportional valve in emergency situations and to either block said actuator in its actual position or to bring said actuator in a predefined safe position.

    Abstract: The feedwater preheating system includes a feedwater tank and a constant volume recirculation pump. The feedwater tank is adapted to store the feedwater. The feedwater tank includes feed and return lines. The feed line is adapted to feed the feedwater to the HRSG, and the return line enables returning of the feedwater into the feedwater tank. The return line precludes a control valve, and is configured to the feedwater tank to reduce component loss while feedwater recirculation. The constant volume recirculation pump is configured in the feed line to recirculate the feedwater between the HRSG and the feedwater tank. The pump is capable of recirculating the feedwater at constant speed and volume to reduce heat loss while feedwater recirculation, as against the prior art feedwater preheating systems.

    Abstract: The invention relates to a cooled wall segment in the hot gas path of a gas turbine, particularly to a cooled stator heat shield. Such components have to be properly cooled in order to avoid thermal damages of these components and to ensure a sufficient lifetime. The wall segment according to the invention includes a first surface, exposed to a medium of relatively high temperature, a second surface, exposed to a medium of relatively low temperature, and side surfaces connecting said first and said second surface and defining a height of the wall segment. At least one cooling channel for a flow-through of a fluid cooling medium extends through the wall segment. Each cooling channel is provided with an inlet for the cooling medium and an outlet for the cooling medium. The at least one cooling channel includes at least two heat transfer sections, a first (in the direction of flow of the cooling medium) heat transfer section extending essentially parallel to the surface of relatively high temperature in a first distance and a second heat transfer section extending essentially parallel to the surface of relatively high temperature in a second distance, whereby the second distance is lower than the first distance.

    Abstract: The present disclosure refers to a method for operating a gas turbine with sequential combustors having a first-burner, a first combustion chamber, and a second combustor arranged sequentially in a fluid flow connection. To minimize emissions and combustion stability problems during transient changes when the fuel flow to a second combustor is initiated the method includes the steps of increasing the second fuel flow to a minimum flow, and reducing the first fuel flow to the first-burner of the same sequential combustor and/or the fuel flow to at least one other sequential combustor of the sequential combustor arrangement in order keep the total fuel mass flow to the gas turbine substantially constant. Besides the method a gas turbine with a fuel distribution system configured to carry out such a method is disclosed.
