Boiler

A process subsystem that uses a fired fuel or waste heat to turn condensate, or liquid water, into high-pressure steam; a device composed of piping, tubes, drums, and support structures designed to absorb heat from a fired fuel source, such as oil, gas, or coal, to generate steam. The generated steam is piped to locations where it can be used to run steam turbines or provide heat for processes. After use, the steam is converted back to water and returned to the boiler for reuse.
