Boiler simulation
1 inlet (feedwater) -> 1 outlet (steam)
Governing equations
The exact equations the solver works for a boiler — the same math shown in the app's "Theory" panel, not a black box.
- Q_{abs}
- heat absorbed by the water [W]
- Q_{fired}
- fuel heat input [W]
- F
- molar flow [mol/s]
- h_{steam}
- outlet steam enthalpy [J/mol]
- h_{feed}
- feedwater enthalpy [J/mol]
- \eta
- boiler efficiency (fired->absorbed)
- T_{sat}(P)
- saturation temperature at the outlet pressure [K]
- \Delta T_{superheat}
- degrees of superheat above saturation [K]
Parameters
outlet_pressure [Pa, default inlet]; outlet is saturated steam unless superheat [K] or outlet_temperature [K] is given; efficiency [0-1, default 0.85] fired->absorbed. Reports duty [W absorbed], fired_duty [W]. Use SteamPkg/IAPWS thermo
