The control characters of feed water for supercritical 600 MW unit is a complex and frequently varying object with multiple variables.The features of feed water regulation are related to both load control and temperature control
the feed water control system adopts a mode of cotrolling the ratio between fuel and feed water
and then through decoupling circuit of fuel and feed water to ensure an approprate fuel-water ratio.The stability of fuel-water ratio again ensures the basic stability of superheated steam temperature and the boiler pressure.
