Description
図1はこの発明の一実施の形態に係る蒸気品質モニタリング装置を示している。
ボイラ2からの供給用蒸気S1は、供給用蒸気ラインL1から蒸気配管L2を介して蒸気サンプリングユニットY1に導かれる。この供給用蒸気S1は、蒸気サンプリングユニットY1において、冷却水Rにて冷やされて凝縮水Gに変えられる。この場合、冷却器10出口の凝縮水Gの温度は温度計14で計測され、この温度が設定温度になるように、コントローラ18が冷却水量調整弁17を介して冷却器10に流入する冷却水Rの流量を制御する。また、冷却器10出口の凝縮水Gの流量は流量計15で計測され、この流量が設定流量になるように、コントローラ18が流量調整弁16を介して冷却器10に流入する供給用蒸気S1の流量を制御する。したがって、凝縮水Gは、コントローラ18による流量調整弁16と冷却水量調整弁17との制御の結果、設定温度(20℃)、設定流量(120mL/min)で、継続的に計測ユニットY2側に送られる。
