How does a back-pressure turbine reheater work? Thank you for the advice
Pipe heating: 1. Turbine rotation (if available). 2. Heating of the shaft seal pipelines (in cases where air leaks from certain shaft seals or main steam valves into these pipelines, it is necessary to heat them first; otherwise, the safety valves will activate when heating the main steam and exhaust pipelines). 3. Heating of the main steam pipelines. 4. Heating of the exhaust pipelines. All that’s left is to control the rate so as to avoid water hammer. For warming up: just follow the acceleration curve
Reply to 2# Yihu Qiankun: Where exactly is the exhaust heating pipe located in the heating system?
An exhaust warm pipe is used to seal the steam exhaust.
