[TRNSYS-users] Rankine cycle simulation by using CHP library TESS

[Jeff Thornton]

Jiyun,

The steam boiler component can be used to heat water to a known condition (given capacity restraints) and then acts like a superheater or evaporator - or both.

Is this TESS library can be used to simulate the component of a coal fired boiler (e.g. superheater, evaporator)?

This HP stage turbine has two extraction steam, with extraction pressure at 54.41 and 34.62 bar, and the inlet pressure and temperature of this turbine is 167 bar and 537 C. When I put the paramaters of this turbine as the input into the Input sheet of this module, there is a mistake when I run this module. It shows that
