Impact of steam generator start-up limitations on th

A dynamic model of a parabolic trough power plant was developed and integrated with a logic controller to identify start-up limitations, and subsequently the dynamic model was integrated in a techno-economic tool previously developed by the authors. The plant was analysed under two different operating strategies, namely solar-driven and peak-load.

Impact of steam generator start-up limitations on th

Two of the key components are the steam generator and steam turbine and the rates at which they can reach operational speed are limited by thermo-mechanical constraints. This paper presents an analysis of the effects of the thermal stress limitations of the steam generator and steam turbine on the power plant start-up, and quantifies their

Water Filtration in Power Generation - Delta Pu

2015-3-20 · THE STEAM POWER CYCLE: BASIC A steam power plant is comprised of a closed loop. The power generation cycle is one of generating steam, sending the steam to a turbine, cooling the steam back to water, and then reheating the water right back up again in a boiler. Figure 1 shows a simplified version of this loop, starting at the boiler, and con-
