Forced Circulation for Supercritical or Subcritical Boilers

This makes the task of material selection and circulation design easy. Another advantage of this natural circulation is that circulation rate increases either when pressure decreases or when heat flux increases. The former enables inherent flow stabilization during load rejection as long as the level of water is correctly controlled in the drum.

Forced circulation boiler — Wikipedia Republished // …

2018-10-31 · A forced circulation boiler is a boiler where a pump is used to circulate water inside the boiler. This differs from a natural circulation boiler which relies on current density to circulate water inside the boiler. In some forced circulation boilers, the water is circulated twenty times the rate of evaporation.
