Download: Modernization approach for subcritical steam turbine units based on the recent steam turbine modernization experience in China
Many existing Steam Power Plants (SPP) designed for base-load operation have to change to flexible mode, requiring optimized startup performance. As many of the plants have already completed the designed lifetime, it is not a feasible option to run these plants in flexible mode. The option left is shifting to flexible mode only after the old turbines are modernized using state-of-the-art materials and technology-enhanced components such as blades, sealings, casings & rotors. The paper shows a real customer case in China.
