A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a boiler which converts it into high pressurized super heated steam. This high energized steam passes through steam turbine (a mechanical device which converts flow energy …
To evaluate the influence of molten salt thermal storage on the flexibility of the power plant, the output power change ratio is defined as (12) β op = Δ W W 0 × 100 %, where ΔW denotes the additional output power during the charging or discharging process, MW; and W 0 is the rated load of the power plant, MW.
