Boiler circulation systems: natural circulation and forced

Boiler circulation systems: natural circulation and forced circulation. For both, steam drum systems as well as once-through steam generators (OTSG) systems, we must have uninterrupted flow of water through the tubes in order for the system to continuously generate steam. For an OTSG system, water travels only one time (single pass) through the boiler tubes before being converted to steam and sent …

How to Destroy a Boiler -- Part 1 - National Board

Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum.

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.
