Unit of competency
Modification History
Release 1. This is the first release of this unit of competency in the UEP Generation Training Package. |
Application
This unit involves the skills and knowledge required to operate, inspect and monitor Heat Recovery Steam Generator (HRSG) hot gas control systems. HRSGs are used to recover heat from a hot gas streams which is then supplied to a steam turbine to generate additional electric power. The hot gas control system is used operate the internal gas return and/or bypass system in the HRSG. Competency in this unit requires the ability to plan work, operate heat recovery steam generator plant, test heat recovery steam generator plant, analyse heat recovery steam generator plant faults, monitor and inspect heat recovery steam generator plant and complete all documentation. Individuals will, in general, work under supervision, in a power generation facility as an operator. Power generation plant operators are typically trained and authorised to isolate, prepare plant and issue permits to work. No licensing, legislative or certification requirements apply to this unit at the time of publication. Note: Workplace practice The application of the skills and knowledge described in this unit may require a licence or training permit to practice in the workplace where work is carried out on gas and electrical installations. Additional conditions may apply under state and territory legislative and regulatory licensing requirements. |
