    摘要： A cooling system includes a first circuit (A) configured to cool a combustion engine (2) and a second circuit (B) configured to cool a condenser (19) in a WHR system. The second circuit (B) has a second radiator (16), a first inlet opening (B1i) at which the second circuit (B) receives a coolant from a first position of the first circuit (A), a condenser inlet line (18) configured to direct coolant to the condenser (19) and an outlet opening (Bo) at which the coolant is directed back to the first circuit (A). The second circuit (B) further has a second radiator bypass line (14) directing coolant past the second radiator (16), and a second valve device (13, 13′) configured to distribute the coolant between the second radiator (16) and the second radiator bypass line (14) such that a coolant mixture is received in the condenser inlet line (18) which is able to cool the working medium in the condenser (19) to a desired condensation temperature.

    摘要： A steam conditioning system for discharging bypass steam into a condenser of a steam powered generating plant and other uses. The system includes a steam conditioning device comprising an inner evaporative core and an outer shell. The core may be formed of a tubular piping section disposed at least partially inside the outer shell forming an annular space therebetween. An inlet end of the core receives steam from a piping header fluidly connected to an upstream desuperheating pressure reducing station which injects liquid coolant into the steam stream. Steam discharges through the core outlet end into the outer shell, reverses direction, and flows into the condenser. In one embodiment, the steam conditioning device may be disposed inside the dome of the condenser except for the inlet end. The device intends to increase flow residence time to evaporate entrained carryover coolant droplets in the incoming steam before release to the condenser.

    摘要： An Ocean Thermal Energy Conversion (OTEC) system having a turbine with an upstream side and a downstream side. Warm water under a partial vacuum is converted into a vapor, the vapor being supplied to the upstream side of the turbine at a pressure controlled by the temperature of the warm water. A condenser is situated on the down-stream side of the turbine to cause the vapor, after passing through the turbine, to undergo a phase change back to a liquid, which can be used as potable water. The condenser is coupled to a source of a cooling liquid, and the pressure of the vapor on the downstream side of the turbine is determined by the temperature of the cooling liquid. A flexible floating solar collector supplies the warm liquid to the upstream side at a temperature higher than normal ambient temperature.

    摘要： A power generation complex plant has a control switch, an overall control unit and a steam bypass facility. The overall control unit determines that a desired steam volume has reached a limit value of the volume of steam to be generated by a steam generating facility. A steam bypass facility control unit adds a bias value B1 to a control command value V4 of the steam bypass facility to generate a new control command value V5 when the desired steam volume is determined to have reached the limit value. The steam bypass facility control unit then controls the volume and pressure of steam passing through the steam bypass facility on the basis of the new control command value V5 so that no switch of control may be made in the control switch.
