Abstract: Abstract:Taking two domestic 600MW direct aircooling subcritical units as example, the energysaving effects of the two units under different steam seal combinations and different gap settings of HP and IP cylinders were compared. Combining with practice, the gap set range for steam seal reformation was proposed, which can be used as reference for similar power plants in steam seal reformation.
