  • Control Engineering | Supercritical Control

    Unlike a drum-type boiler, the once-through, supercritical boiler does not have a large steam drum to store energy. Because there is no energy reserve, the control system must match, exactly and continuously, feedwater flow and boiler firing rate (both fuel and air) to the turbine's steam energy needs, to deliver the desired generator power.
