Description
This unit involves the skills and knowledge required to start up a Heat Recovery Steam Generator (HRSG) for service.HRSGs are recovery heat exchangers that retrieve the heat from hot gasstreams which are then supplied to steam turbines to generate additional electric power. Placing an HRSG in-service will require the entry of a heating medium and the control of water within the steam and/or water drum. It includes monitoring the flow and quality of feedwater, steam pressure and temperature increases and metal temperatures within HSRG design limits so that the HRSG is supplying a constant flow of steam at the required temperature and pressure.Competency in this unit requires the ability to plan and prepare start up, operate HRSG plant during start up, test and analyse HRSG system faults and complete 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.
Notes
