Mathematical Problems in Engineering - Hindawi

2014-4-10 · For the operation of the supercritical once-through boiler generation units, the control of the temperature at intermediate point (IPT) is highly significant. IPT is the steam temperature at the outlet of the separator. Currently, PID control algorithms are widely adopted for the IPT control. However, PID cannot achieve the optimal performances as the units’ dynamic characteristic

SUPERCRITICAL COAL FIRED POWER PLANT

2019-2-4 · The supercritical plant needs 'once-through' boiler, where as 'drum' type boiler is required by sub-critical power plant. In fact, once-through boilers are better suited to frequent load variations than drum type boilers, since the drum is a component with a high wall thickness, requiring controlled heating.
