Modelling and simulation of a coal-fired power plant for

Dec 15, 2017· Compared to gas fired power plants, the start-up process in coal-fired power plants is much more complex on the firing side. Instead of continuously increasing fuel flow, coal mills need to be heated up before starting. Therefore, oil burners are used to heat up the boiler system and provide ignition conditions for the coal fire.
