high cr shell liners for coal fired power plants
2 Modelling of coal-fired power plants flexibility retrofits
Originally, coal-fired power plants are designed for baseload operation which is unable to operate at a low load and change output rapidly . At present, the hard coal-fired power plants can reach the minimum load with 25–40% of nominal load and the lignite-fired power plants are usually not able to operate in <50–60% of nominal load.
