About this lesson
In a regenerative cycle, small amounts of steam are bled from the turbine to heat the feed water before it enters the boiler. Less fuel heat is then needed at low temperature.
How it works
- Steam expands through the turbine.
- At several points a little steam is bled off.
- The bled steam heats the feed water in feed-water heaters.
- Hotter feed water enters the boiler, so less fuel is burned to bring it to steam.
