Design Optimization and Dynamic Simulation of Steam Cycle
Introduction. Steam cycles have been used for electric power generation from coal since the early 1900’s. These first coal fired power units featured outputs in the range 1–10 MW and the steam generator already included an economizer an evaporator and a superheater Harvey et al. 2020 .According to the same reference the first steam cycle had an efficiency of only
