Boiler circulation systems: natural circulation and forced

Boiler circulation systems: natural circulation and forced circulation. For an OTSG system, water travels only one time (single pass) through the boiler tubes before being converted to steam and sent to the steam turbine generator set for producing electricity. On the other hand for steam-drum systems, water has to travel many times (multiple passes) through the tubes before it leaves as steam.
