Abstract: The purpose of the present invention is to maintain the intake pressure of a water supply pump at an operable pressure. A boiler is provided with: condensate pumps (a condensate pump and an auxiliary condensate pump); a branch line that causes water delivered by the condensate pumps to branch; a drum (a low-pressure drum) that is connected to one (a low-pressure branch line) of two lines into which the branch line branches; and a water supply pump that is connected to the other (a high-pressure branch line) of the two lines into which the branching line branches and that pumps water to an evaporator (a high-pressure evaporator). The boiler is additionally provided with pressure applying means that guides a portion of the water in the drum to the water supply pump side when the intake pressure on the inlet side of the water supply pump has become lower than a predetermined pressure.

Abstract: The present invention relates to a Rankine system comprising a valve including a valve member. The valve member is provided with a valve controlling element in the form of an elongated tapered end portion with a tip end facing the duct, wherein the tapered end portion is arranged to be inserted through the opening and into the duct as the valve member is moved towards the valve seat. The actuator is configured to hold the valve member in at least one intermediate position between the first and second end positions, where the tapered end portion occupies a portion of a cross-sectional fluid through-flow area defined by the duct so as to partly restrict a flow of fluid through the duct.

Abstract: A gas turbine plant including a gas turbine and a compressor is provided with a steam turbine plant including a steam turbine and a condenser, and, an exhaust heat recovery boiler. Steam from the exhaust heat recovery boiler is directly flown to the condenser of the steam turbine plant through a bypass control valve. A pressure sensor detects pressure in a turbine bypass system. A controller outputs, based on a set value from an input device and a process value from the pressure sensor, an open level instruction value to the control value so as to make the process value consistent with the set value in a predetermined sampling cycle. A corrector corrects the set value from the input device in a direction in which the open level instruction value decreases when the open level instruction value from the controller becomes a value that substantially fully opens the control valve.

Abstract: A system for providing supercritical steam including a first boiler that generates steam via combusting a first fuel, and a second boiler fluidly connected to the first boiler via a conduit which heats the generated steam to supercritical steam temperatures via combusting a second fuel. A first temperature of the conduit may be below a critical corrosion temperature and a second temperature of the conduit is greater than or equal to the critical corrosion temperature. A combined carbon emission rate of the first boiler and the second boiler may be less than a combined carbon emission rate of generating and heating the steam to supercritical steam temperatures using boilers that only combust the first fuel. The first boiler may be fluidly connected to a heat exchanger that heats the generated steam to a supercritical steam temperature via a flue gas produced by a gas turbine.

Abstract: A gas turbine system includes a compressor protection subsystem; a hibernation mode subsystem; and a control subsystem that controls the compressor subsystem and the hibernation subsystem. At partial loads on the turbine system, the compressor protection subsystem maintains an air flow through a compressor at an airflow coefficient for the partial load above a minimum flow rate coefficient where aeromechanical stresses occur in the compressor. The air fuel ratio in a combustor is maintained where exhaust gas emission components from the turbine are maintained below a predetermined component emission level while operating at partial loads.

Abstract: A control device includes a mode-recognizing unit that recognizes whether a start mode of a steam turbine is a cold mode in which a temperature of a steam contact portion of the steam turbine is lower than a predetermined temperature or a different start mode in which the temperature of the steam contact portion is equal to or higher than the predetermined temperature, a first opening generator that generates a first degree of opening greater than a second degree of opening in the different start mode as a degree of opening of an intake air regulator of a compressor in a period after generation of steam from an exhaust heat recovery boiler is started and before supplying of the steam to the steam turbine is started, and a command output unit that outputs a command corresponding to the first degree of opening to the intake air regulator.

Abstract: A turbine of an organic Ranking cycle (ORC) is described. The turbine includes a shaft supported by at least two bearings and a plurality of axial stages of expansion, defined by arrays of stator blades alternated with arrays or rotor blades. The rotor blades are sustained by corresponding supporting disks. A main supporting disk is directly coupled to the shaft in an outer position with respect to the bearings, and the remaining supporting disks are constrained to the main supporting disk, and one to the other in succession, but not directly to the shaft. Some of the remaining supporting disks are constrained to the main supporting disk and cantileverly extend from the same side of the bearings that support the shaft, so that the center of gravity of the rotor part of the turbine is shifted more towards the bearings.
