Subcritical Coal-Fired Power Plant Flowsheet (steady state

Some unit models are treated as the steady-state models on the dynamic flowsheet. For example, the boiler fire-side model is assumed as steady-state since the flue gas density is low and so is the residence time (2-3 seconds). All turbine stages, condensers and pumps are modeled as pseudo-steady-state.
