Operating point (of the plant)
The operating point describes the operating parameters within which a plant or boiler is operated
in its nominal range. In a steam boiler, for example, these parameters would be output, pressure,
and temperature.
The design data may be a lot more stringent, however.
A boiler that is operated at 145 psi (10 bar) and 356°F (180°C) may be designed to withstand a
pressure of 870 psi (60 bar) and a temperature of 527°F (275°C), for example, which is therefore
not necessarily its operating point.
