摘要： Apparatus and method of monitoring the performance of a steam power plant, wherein the monitoring is made through a calculation of the performance from detected data representing the states of operation of various parts of the plant, such as feedwater flow rate, steam pressure, steam temperature and the level of the load imposed on the plant. The method has a function for judging the fluctuation of the load and a function for judging the duration of steady state of the load. When the rate of fluctuation of the load is below a predetermined reference and this state of load lasts over a predetermined time length, it is judged that the data detected during this time length are valid as the data for monitoring of the performance and the performance is calculated from these data to permit the monitoring. The apparatus comprises a first comparator for comparing the rate of fluctuation of the load detected by the detector for detecting the load with a predetermined reference value, a second comparator for comparing the detection duration or time length of the detection obtained from the detector for detecting the load with a predetermined reference value, and judging means adapted to permit the detected data to be delivered to the plant performance calculation means for the calculation of the heat rate of the plant, in accordance with the outputs from the first and the second comparators, when the rate of fluctuation of the load is below the level of the reference value and this state of the load lasts over a predetermined time length.
摘要翻译：监测蒸汽发电厂的性能的装置和方法，其中，通过从表示设备各部分的运行状态的检测数据计算性能来进行监测，例如给水流量，蒸汽压力，蒸汽温度以及施加在工厂上的负载水平。该方法具有判断负载波动的功能和判断负载稳态持续时间的功能。当负载的波动率低于预定参考值并且这种负载状态持续超过预定时间长度时，判断在该时间长度期间检测到的数据是有效的，因为用于监视性能和性能的数据是从这些数据计算，以便进行监测。该装置包括：第一比较器，用于将用于检测负载的检测器检测到的负载的波动率与预定参考值进行比较;第二比较器，用于比较从检测器检测到的检测器的检测持续时间或检测时间长度，负载预定参考值;以及判断装置，适于根据来自第一和第二比较器的输出，将检测到的数据传送到工厂性能计算装置以计算工厂的热量，当时负载的波动率低于参考值的水平，并且负载的这种状态持续超过预定的时间长度。

摘要： An object of the present invention is to provide a turbine protection device which can interrupt backflow from a deaerator to a turbine completely even if a check valve provided between the deaerator and the turbine can not interrupt the steam flow between the deaerator and the turbine completely. In order to achieve the above object, a control unit sends commands to a shutdown valve device so as to close the shutdown valve device when a differential pressure resulted from subtracting a pressure of a extraction steam from a pressure within the deaerator becomes greater than or equal to a first predetermined value. As a result, the backflow from the deaerator to the turbine is interrupted by a stop valve of the shutdown valve device.
摘要翻译：本发明的目的是提供一种涡轮机保护装置，其即使在脱气器和涡轮机之间设置的止回阀也不能完全中断脱气器和涡轮机之间的蒸汽流动，因此可以完全中断从脱气器到涡轮机的回流。为了实现上述目的，当从脱气器内的压力减去提取蒸汽的压力而产生的压差变得大于或等于一个时，控制单元向关闭阀装置发送命令以关闭关闭阀装置到第一预定值。结果，从脱气器到涡轮机的回流被关闭阀装置的截止阀中断。

摘要： A waste heat recovery boiler system has a plurality of waste heat recovery boilers each having a main steam generator and a reheater capable of generating main steam and reheat steam by heat derived from a hot waste gas introduced into the waste heat recovery boiler. The flows of main steam from the main steam generators are joined to form a single flow of main steam to be used in an external installation, and the flows of reheat steam from the reheaters are joined to form a single flow of reheat steam to be used in the external installation. The steam discharged from the external installation is distributed to the reheaters. Flow rate controllers are provided for controlling the flow rates of the steam through the reheaters in relation to the hot waste gas supplied to the respective waste heat recovery boilers.
