Bright steam has reached dry saturation state, and the degree of superheat has completely eliminated.Due to moisture detector 54, need to detect a parameter (wet
Degree), so testing cost is low；Only it need to detect whether liquid water occur, required precision is low；Without calculating detection parameters,
Detection is more sensitive quick；Even if cause to spray into extra moisture, the excessive moisture due to 54 failure of moisture detector
It can be discharged by the drainage arrangement of 52 bottom of compressor, it is saturation state to ensure 52 outlet vapor of compressor, and makes compressor 52
Always it is in a safe condition.
