plc controll boiler steam generator

CHAPTER 3: STEAM GENERATOR CONTROL

In athermal electric power plantthe steam generators (often referred toas "boilers") are a critical energy link between the primary heat source (fossil ornuclear) and the turbine. In nucleargenerating stations the boiler level control system mustfunction properly in orderto provide a continuous heat sinktothe reactor.
