Description
This unit involves the skills and knowledge required to operate an in-service Heat Recover Steam Generator (HRSG). Operation of the HRSG, with or without supplementary firing, will be required through the full range of output, up to and including the maximum continuous rating.A HRSG is a heat exchanger that retrieves heat from hot gasstreams which is then supplied to steam turbines to generate additional electrical power. Competency in this unit requires the ability to plan work, carry out operation of HRSG system, test HRSG operation, analyse HRSG system faults, inspect and monitor HRSG system 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 practiceThe 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.
