Typically, the negative effects of the flow distribution are negligible for the two-pass superheater modules, as the tube pressure drop is substantially higher than the header loss, even at low loads.

As long as the condenser is not yet ready, the boiler relies only on superheater start-up vents sized ad hoc. Only the HP drum pressure needs to be controlled, and no limitations are imposed on IP ...

Heating surfaces that function as preheating, evaporator, or steam generating, superheater, and reheater are shown as process lines in Figure 1, an h-p, enthalpy versus pressure diagram.

Boiler retubing added to Pere Marquette No. 1225’s ongoing superheater repairs, with additional work to include interior ...
