neqsim-fired-heater-duty-screening

Use the FiredHeaterDutyModel evaluate method with mass flow, specific heat, inlet and outlet temperatures, and radiant area. It returns process duty from Q = m*cp*dT, fired duty from the thermal efficiency, and fuel rate from the fuel heating value.

The model divides process duty by radiant area to get average radiant flux, then computes the ratio to the allowable flux, defaulting to 37 kW/m2. Ratios at or above 1.0 return high-flux, at or above 0.85 return watch, otherwise ok.

No, this is an educational screening placeholder only. It assumes constant specific heat and assigns all duty to the radiant section, so validated methods such as API 560, NeqSim FiredHeater classes, and qualified review are required for real design.

No, the model runs standalone with no required dependencies. It only checks whether the neqsim package is available and reports that flag in the result, without calling NeqSim functionality.

All inputs must be finite and positive, outlet temperature must exceed inlet temperature, and thermal efficiency must be in the interval (0, 1]. Violating any of these raises a ValueError naming the offending parameter.
