摘要： PROBLEM TO BE SOLVED: To reduce a thrust load of a steam turbine.
SOLUTION: The combined-cycle steam turbine containing a system which forms a flow of process extraction contains a control system (31) for offsetting a thrust effect of a flow of extraction at an air exit of a high-pressure section of the steam turbine. The control system (31) contains valves (12, 14, 16) for deflecting HP exhaust packing leak off steam from a lower-pressure stage to a higher-pressure stage of an intermediate pressure section of the steam turbine and a piping structure (10).

摘要： PURPOSE:To conduct lowering of turbine load without giving external turbulence to the system by shutting off purge to the high pressure supply water heater on the maximum pressure side in advance to pressure lowering when turbine load is lowered to a limit load. CONSTITUTION:When the water level of the high pressure feed water heater of a steam turbine power plant becomes abnormally high, it is detected by the AND circuit section 25 through level switches 14-17. The extraction to the high pressure feed water heater is shut off by this detection, and thereafter the steam control valve is slowly throttled to lower turbine load to a limit load. After the limit load is reached, the extraction shut-off to the high pressure feed water heater on super high pressure side is again released. With this arrangement, the turbine load is slowly lowered with the turbine itself under protection, suppressing turbulence to the outside of system.

摘要： PURPOSE:To enhance the internal efficiency of a steam turbine and enlarge the steam extraction control range by providing a plurality of steam extraction adjusting valves and performing steam extraction by suitably switching each adjusting valve, thereby reducing pressure loss caused by throttling the adjusting. valve. CONSTITUTION:Two steam extraction passages 7 and 8 are arranged in parallel, rang ing from the high pressure side to the low pressure side of a steam turbine 1, and the end of each of which is connected to a header 9, The steam extraction passages 7 and 8 are provided with steam extraction adjusting valves 10 and 11 respectively interposed therein, while check valves 12 and 13 are interposed downstream therefrom. When the steam turbine 1 is run under a low load, if extracted steam pressure at a measuring point 14 on the high pressure side is equal to or higher than the header pressure and moreover the extracted steam pressure at a measuring point 15 on the low pressure side is lower than the header pressure, the steam extraction adjusting valve 11 is closed while the steam extraction adjusting valve 10 is opened, thereby extracting the steam having the set pressure from the header 9. When the extracted steam pressure at the measuring point 15 becomes higher than the header pressure, the steam extraction adjusting valve 10 is closed while the steam extraction adjusting valve 11 is opened.

摘要： PURPOSE:To operate a turbine most economically, safely and smoothly and thereby make the cost of power generation ever so inexpensive, by monitoring a steam quantity flowing into a condensor, while letting the irreducible minimal steam required flow in the condenser all the time, and controlling it so as to make the steam quantity a constant value. CONSTITUTION:A steam quantity flowing into a condenser (at the side of a low-pressure turbine) is detected by a valve lift detector 1 attached to an extraction valve 12, comparing this detected value with the setting value and operating it with an operator 2, and when a signal value gets out of the setting value, a signal is transmitted to a governor motor 4 from a control unit 3 connected to the operator 2, moving a govenor, and output of a turbine is altered. With this alteration, the steam quantity flowing into the condensor is controlled so as to cause it to become a constant value without altering pressure of the extraction steam flowing in a process. In order to make this operation safely and smoothly, protector devices 5, 5' and 5'' are built in the control unit, and a warning signal is given forth according to circumstances and locking takes place. Therefore, energy-saving operation is achievable and, what is more, the cost of power generation is reducible.

CONSTITUTION:The speed of a bleed turbine 2 is detected by a speed detector 4 and input into an arithmetic means 12 together with the set value of a speed. load setting device 11. The steam pressure in a bleed line is detected by a pressure detector 5 and input into an arithmetic means 15 together with the set value in a bleed-pressure setting device 14.

Each output of the comparators 25 and 26 on the max. flow-rate side drives a signal switch 30 on an upper limit bias 29 side, and the output of a comparator 27 on the min. flow-rate side drives a signal switch 32 on a lower limit bias 31 side. Thus, a turbine can be operated automatically in a prescribed limit range.
