| PURPOSE:To enable to control in quick response to the required value of feed water flow rate by a method wherein a spare steam pressure control signal generator is provided in a steam turbine control device for driving a feed water pump and a spare control signal is used when the generated output of a power plant falls down abruptly. CONSTITUTION:Steams are supplied from high pressure main steam supplying system 52 and low pressure extracted steam supplying system 50 through a high pressure and a low pressure regulating valves 48 and 46 to an auxiliary steam turbine 12 to drive a feed water pump 10. Normally, the regulating valves are controlled in proportion to the deviation between the control signal sent from a feed water control device 32 and the control signals sent from turbine rotational frequency detectors 18 and 20. However, because when the generated output of a power plant falls down abruptly, a contactor 36 is changed-over so as to bring a spare steam pressure control signal generator 54, at which the control signal for the high pressure regulating valve 48 is set in advance, into actuation in order to supply steam from the main steam supplying system 52, the steam pressure of the turbine can be prevented from abruptly falling down and consequently ensuring the necessary feed water flow rate. | ||||||

| Transforming any heat sources to electric power, comprising a closed-cycle charged refrigerant loop. Low-pressure refrigerant fluid is pumped at 10 to 15 degrees F. higher of the ambient temperature through a heat exchanger heated by the heat of the gas outlet from the expander then to the boiler (heat exchanger) to boil the refrigerant liquid into a high-pressure and high temperature superheated by a few deg. F. gas (depending on the kind of refrigerant). Heated/pressurized refrigerant gas is inlet into an expander to power an output shaft during the expansion of the pressurized to a cooled gas. Cooled gaseous refrigerant with still high temperature is inlet to small heat exchanger to heat up the pumped liquid refrigerant before inlet to the boiler. The lowered temperature gas is condensed in condenser to liquid at low pressure and 10 to 15 degrees F. higher of ambient temperature media, and recycled by a pump to the heat exchangers. The refrigerant gas mass flow pressure drop spins the expander shaft for direct mechanical power take-off, or coupling to a synchronous or inductive generator to produce electricity. The electricity can be used locally, stored or fed to the grid. | ||||||
