Water Tube Boiler - Definition, Components, Working

The working principle of water tube boiler is thermal siphoning (circulation of natural water). Basically, this type of boiler includes two drums namely steam, lower or mud drum. The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the

Water-Tube Boilers - Babcock Wanson

2020-4-9 · Operating Principle Water is circulated inside the tubes of the boiler, with the heat source surrounding them. The heated water rises into the steam drum where saturated steam is drawn off the top of the drum. Cool water at the bottom of the steam drum returns to the feedwater drum via large-bore 'downcomer tubes', where it pre-heats the feedwater supply. (In large utility boilers, the

Boiler circulation systems: natural circulation and

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 to the steam turbine generator set for producing electricity.
