Natural Circulation - an overview | ScienceDirect Topics

Natural circulation is caused by the density difference between saturated water and heated water partially filled with steam bubbles. In a natural circulation unit the water tubes are connected to a loop, Fig. 4.3. Heat is applied to one leg, called the raiser tube, where the water–steam mixture flows upward.

An Introduction to Treatment of Steam Boiler Water

A steam boiler is an enclosed vessel that holds water and is heated by an external source that converts the water to steam. All steam boilers contain tubes that separate the water from the heat source. Steam boilers are described in this publication. 1.1.1 TYPES OF STEAM BOILERS. Boilers are classified by two criteria: 1) operating

Forced circulation boiler - Wikipedia

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.
