55. Please briefly describe the steam flow direction for the flue gas compressor seal.
The steam from the shaft end seal of the smoke extractor enters the casing, flows radially along the back side of the secondary disc, and after cooling, enters the flow channel.
The sealing of the smoke extractor’s seal mechanism is of the labyrinth type, utilizing sealing teeth for protection; as a result, there is some air leakage at the shaft seal of the smoke extractor, with greater leakage occurring when the gap is larger. The shaft seal of the flue gas extractor features a two-stage sealing system: the inner layer is a steam seal, while the outer layer is an air seal. There is an exhaust pipe on the sealing unit, through which excess steam and air are removed. Control the exhaust volume based on pressure difference
