Venting of the steam seal tube in Hangzhou Steam Turbine’s condensing type turbines
Thread Content
Why is the amount of vapor escaping from the steam seal exhaust at the high-pressure side very small, while it is significant at the low-pressure side?
The gas seal at the high-pressure side is designed to prevent gas from escaping, while that at the low-pressure side serves to prevent air from entering. Both serve the purpose of acting as gas seals. Relatively speaking, there is always some leakage at the high-pressure side – as long as there is gas present that’s fine – but the seal at the low-pressure side needs to be stronger in order to prevent air from getting in
The answer to your question has already been given on the 2nd floor, so I won’t go into further detail. In fact, what was mentioned before – the four understandings and three skills – is still very necessary. Learning* is a systematic process: by understanding the principles and then knowing the structure, one can become clearer about the function of each component and why it has been designed that way. Keep it up, OP!
