Mar 02, 2021 · In natural circulation boilers, the circulation of water is by natural convection currents, which are set up during the heating of water. In most steam boilers, there is a natural circulation of water. #8 Forced Circulation Boilers. In forced circulation boilers, there is a forced circulation of water by a Centrifugal pump, which is driven by

Why is natural circulation only possible in subcritical

A once through boiler is smaller in size and weighs less in comparison to a natural circulation boiler. 6. Easy control of steam temperature during start-up and shut down (which is very advantageous for start-up of boiler and turbine). 7. Greater freedom in arrangement and location of heating surfaces. ADVERTISEMENTS: 8.
