modelControllerFuelForBurner
Controller to control the fuel mass flow rate for the burner
Extends from TransiEnt.Basics.Icons.Controller (Icon for controller).
Information
1. Purpose of model
This is a controller to control the fuel mass flow rate for the burner for a target system outlet temperature.
2. Level of detail, physical effects considered, and physical insight
The temperature at the system outlet is measured and compared to the target value. The fuel is controlled using a P, PI, PD or PID controller.
3. Limits of validity
(no remarks)
4. Interfaces
T_flueGas: Measured flue gas outlet temperature
m_flow_fuel: output for the fuel mass flow rate (positive sign)
