Solar Aided Power Generation (SAPG) is the most efficient and economic ways to hybridise solar thermal energy and a fossil fuel fired regenerative Rankine cycle (RRC) power plant for power generation purpose. In such an SAPG plant. the solar thermal energy is used to displace the extraction steam by preheating the feedwater to the boiler. The displaced/saved extraction steam can. https://www.roneverhart.com/Liftmaster-CSL24UL-Slide-Gate-Opener/
