Performance assessment of supercritical power plant based oil fuel under sliding-pressure operation
Energetic and exergetic analyses of a 626 MWe supercritical power plant-based mazout oil-fired are carried out to assess the system's performance. The energy losses and exergy destruction are evaluated for each system component using real actual data. The results show that the boiler is the primary source of irreversibility with 88.62% of the total exergy destruction. The intermediate pressure turbine maintains an exergy efficiency of 97% at 100%-load. Moreover, the maximum thermal efficiency is achieved at 100%-full load by 44.85% whereas, the maximum overall exergy efficiency of 40% is acquired at the maximum continuous rate condition of 105%-load.
