Claims (1)
- 蒸気配管に一次側蒸気で発電することによって一次側蒸気を減圧された二次側蒸気とする蒸気タービン発電機と流量制御弁と質量流量計を配置し、上記蒸気タービン発電機の発電量を検出する電力計を設け、上記蒸気タービン発電機の一次側蒸気の圧力並びに二次側蒸気の圧力及び温度を夫々検出するセンサを設け、上記流量制御弁の開度を上記センサによって検出される上記二次側蒸気の圧力及び温度に基づいて二次側蒸気が過熱蒸気となるように制御すると共にその二次側蒸気が過熱蒸気になった状態において上記質量流量計によって検出される質量流量値Gと上記電力計によって検出される電力量Wと上記各センサによって検出される検出値に基づいて算出する一次側蒸気の飽和水のエンタルピI1'及び飽和蒸気のエンタルピI1''と二次側過熱蒸気のエンタルピI2とに基づいて一次側蒸気の乾き度Xを{(I2-I1')+W/G}/(I1''-I1')として算出する制御演算部を設けてなる蒸気乾き度測定装置。
