Optimization of Organic Rankine Cycles for Waste Heat Recovery From Aluminum Production Plants

In an organic Rankine cycle, there are generally two ways to increase the net power output, namely increase thermal efficiency and increase the amount of waste heat recovered

The proposed system consisted of a waste heat recovery unit (WHRU), a thermal energy storage and a power cycle, all connected by a closed loop where a heat transfer fluid

Pressure drop, heat transfer, and tube vibration are all design aspects which need to be assessed for compact waste heat recovery units.. The investigation into these

For different values of the heat demand (produced heat via system) and gas turbine exhaust temperatures (State 1), as well as different working fluids, the

In the transient case, the average power density generated during one silicon casting cycle is in all investigated cases found to be only 7 - 10% of the peak power density as the
