The design institute advises you: The most commonly used type of seal in the petrochemical industry nowadays is the comb-tooth seal; for example, those used by Hangzhou Automobile, and they have significant leakage issues, requiring the use of steam extractors to remove steam. Large-scale units in the power industry almost all use Brayton cycles, and the results are very good. However, it is not suitable for small units. It is said that honeycomb type is better than comb-type, but it doesn’t seem to be used very often.
Honeycomb seals perform very well at the turbine shaft ends
The sealing performance of Bryden is relatively good, but the honeycomb structure tends to wear out easily
