摘要： PURPOSE:To prevent drop in temperature, etc. of a feed water heater caused by depression in turbine bleed during turbine bypass operation by providing a bypass steam supply pipe through which turbine bypass steam is supplied into a feedwater line through desuperheaters. CONSTITUTION:Steam generated in a boiler 1 is guided to successively pass through a high-pressure turbine 5, a reheater 7, an intermediate pressure turbine 10, and a low pressure turbine 11 to carry out work, before it is introduced to a condenser 12 and condensed, and the condensate is returned to a boiler 1 through a heater 15, a degasifier 16, and a heater 18. In a plant of such construction, a bypass steam supply pipe 25 is branched out from a low pressure turbine bypass pipe 22 at a position adjacent to a bypass valve 21 on the lower course. The first and the second bypass-steam supply pipes 25a, 25b are branched from the pipe 25, and desuperheaters 26, 29 are provided in the pipes 25a, 25b respectively. And, the pipe 25a is connected to a high-pressure feedwater heater 18, and the pipe 25b is connected to a low-pressure feedwater heater 15 respectively.

摘要： PURPOSE:To prevent the water level of a condenser from being lowered by correcting a condensate flow rate command value, which is provided based on the water level of a degasifier and the feed-water flow rate, in accordance with the water level of said condenser. CONSTITUTION:In this device, the output signal of an adder-subtractor 13-a, which outputs a deviation between a water level signal from a degasifier water level gage 10 and a water level set value, is proportionately integrated 14-a before adding 15-a the feed water flow rate from a feedwater flow rate gage 8 as a feed forward signal to the above results, and the resultant output signal is made the command signal for the condensate flow rate. A deviation between this command signal and the condensate flow rate gage 9 is obtained by an adder- subtractor 13-b, and the opening of a degasifier water-level control valve 7 is controlled based on this deviation. In this case, further, a condenser water-level gage 17 is provided, its output is fed to an adder 15-b through a function generator 16-a, and added to the output which was proportionately integrated 14-a and the sum is fed to the adder 15-a.
摘要翻译：目的：通过根据所述冷凝器的水位校正基于脱气器的水位和给水流量而提供的冷凝物流量指令值来防止冷凝器的水位下降，。构成：在该装置中，输出来自脱水装置水位计10的水位信号与水位设定值之间的偏差的加法器 - 减法器13-a的输出信号在添加15之前成比例地积分14-a - 作为前馈信号的给水流量计8的给水流量达到上述结果，并将所得输出信号作为冷凝物流量的指令信号。通过加法器 - 减法器13-b获得该指令信号和冷凝物流量计9之间的偏差，并且基于该偏差来控制脱气水位控制阀7的打开。在这种情况下，进一步提供冷凝器水位计17，其输出通过函数发生器16-a被馈送到加法器15-b，并且相加于与成比例地积分14-a的输出，馈送到加法器15-a。
