Abstract
- The Organic Rankine Cycle (ORC) is a promising method for converting thermal energy into electrical power. The National Research and Innovation Agency (BRIN) developed an ORC pilot plant with a power output of 100 kilowatts using heat from waste powerplant exhaust heat at Soreang, Jawa Barat, Indonesia. The working fluid utilized in this pilot plant is n-pentane, a highly flammable fluid; thus, the turbine used must be hermetically sealed. This plant uses a threestage radial outflow and axial inflow turbine that is designed using the analytical/empirical method and validated by numerical simulation analysis. A numerical simulation was conducted by varying the turbine rotation and outlet pressure in order to obtain the turbine performance curve. Through a comparison between analytical calculation and numerical simulation, the turbine's general performance at 8000 rpm is characterized by a pressure ratio of approximately 5.42, a mass flow rate of 3.28 kg/s, and a power output of 41.21 kW. The turbine stage performance typically fails to meet the desired design specifications when initiated at stator 1 and then extended to the remaining stages. In order to achieve a power output of 100 kW, the turbine must undergo a process of redesign or optimization. [ABSTRACT FROM AUTHOR]
