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.

nature circulation types of water tube boiler

Babcock and Wilcox water tube boiler as the name suggests is a water tube boiler and hence works on the principle of thermo siphoning (natural circulation of water). The water at the front portion of steam drum comes in contact with hot gases a=t higher temperatures and so its temperature increases and density decreases.
