Coal-Fired Industrial Boiler Inspection Guide

Improvement in coal quality can'also lead to operating problems in a pulverized-coal-fired boiler. If a nonslagging coal is burned in a boiler designed for a slagging coal, furnace walls may be too clean, and too much radiant heat may be absorbed, which makes it difficult for the superheater to produce the necessary steam temperatures.

5.1. Heat rate improvement depending on steam conditions. The operating efficiency of subcritical plants is about 37% lower heating value (LHV), while that of the supercritical plants is about 40%. For ultra-supercritical units, the operating efficiency ranges from 45% to 48%, or even higher in some cases.
