摘要： PURPOSE:To reduce the volume of gases in a water condensation system and to reduce the exhaust gas pressure of a turbine by utilizing the section in a reservoir which is partitioned by a bladder as a bled gas storage chamber. CONSTITUTION:The reservoir 2 of an accumulator is branched to the pressurizing section (also used as a bled gas storage chamber) 3A and water storage section 3B of the reservoir. And at the time of starting a high pressure gas is introduced into the pressurizing section 3A of the reservoir through a high pressure gas control valve 6 to push a bladder 4, and the boiler water is jetted to a water supply pump and condenser. Right after starting a control valve 6 is changed over so as to connect the pressurizing section 3A and a submarine navigator and the steam generated in boiler pipes is introduced into the water storage section 3B and the bladder 4 is returned to its position before starting to discharge the high pressure gas of the pressurizing section 3A and to close the control valve 6 and a steam valve 7. During the operation the gases left in the condensation system are sucked from the upper section of the water storage section 3B by a vacuum pump 8 and discharged to the pressurizing section 3A. With this arrangement it is possible to reduce the pressure in the water condensition system and to reduce the exhaust gas pressure of the turbine.

摘要： PURPOSE:To increase the volume of a condensation system and reduce the exhaust gas pressure of a turbine by the constitution that a bladder is pushed back to its position before starting by steam pressure. CONSTITUTION:A boiler pipe and the water storage section 3B of a reservoir are connected by a capillary through a steam valve 7. At the time of starting a high pressure gas is introduced into the pressurizing section 3A of the reservoir through a high pressure gas control valve 6 and by its pressure a bladder 4 is pushed up to the position of the partition section between a condenser 1 and water reservoir 2, and the boiler water is jetted out to a water supply pump and condenser through a water storage valve 5. Right after starting the control valve 6 is changed over so as to connect the pressurizing section 3A and a submarine navigator, and the steam generated in boiler tubes is introduced into the water storage section 3B of the reservoir through a steam valve 7 and the capillary and the bladder returns to its position before starting to release completely the high pressure gas of the pressurizing section 3A and close the steam valve 7. And during the operation the bladder 4 is pushed back to its position before starting. With this arrangement the volume of a water condensation system is secured to the maximum degree and the exhaust gas pressure of the turbine is reduced.

摘要： PURPOSE:To increase the volume of a condensation system and reduce the exhaust gas pressure of a turbine by installing inside a bladder push metal made of a shape memory alloy and constituting to push back the bladder to its position before starting. CONSTITUTION:A bladder 4 is installed along the left wall of a reservoir 2 and a bladder push metal 5 made of a shape memory alloy is installed so as to sit along the partition section of the reservoir 2 and a condensation chamber 1. And, at the time of starting a high pressure gas is introduced into the pressurizing section 3A of the reservoir through a high pressure gas control valve 7, and the bladder 4 is pushed up to the position of the partition section to jet out the boiler water to a water supply pump and a condenser through a water storage valve 6. Right after starting a control valve 7 is changed over so as to connect the pressurizing section 3A and a submarine navigator, and the bladder push metal 5 changes by the temperature of the condensed water its shape that follows the shape of the left wall of the reservoir 2 which the bladder push metal 5 has held in memory beforehand, and the high pressure gas in the pressurizing section 3A is released into the body sailing in water to close the control valve 7. And during the operation the bladder 4 is pushed back to its position before starting. With this arrangement the volume of the condensation/system is secured to the maximum degree and the exhaust gas pressure of the turbine is reduced.
