Together with Components 149 and 150, this component forms a component group that allows to model a common steam header. The crucial difference compared to the other components of the type Mixer/Splitter (like e.g. Components 4, 18, 37, 60) is that only Pin 1 has a fixed flow direction (here: inlet). It is true that Pins 2 and 3 are defined as inlet and outlet respectively.
However, they can be both inlet and outlet. This makes the flow direction within the common steam header arbitrary. With negative mass flows M3 and M2 respectively, however, the inlet is implemented at Pin 3 and the outlet at Pin 2 due to the logic defined in EBSILON. In contrast, positive values for M2 and M3 imply the distribution that is “normal“ for EBSILON (Pin 2 represents the inlet, Pin 3 represents the outlet).
The component can be calculated with the following line types:
- Air
- Flue gas
- Steam
- Water (liquid)
- Crude gas
- Oil (with specifiable composition)
- Coal / solid matter
- Gas (fuel)
- User-defined
- 2-Phase liquid
- 2-Phase gaseous
- Saltwater
Depending on the flow distribution that results in the common steam header due to the mass balance, three situations are possible:
Situation 1: Mixing of Flows 1 and 2 to Flow 3 – all mass flows are positive
Situation 2: Mixing of Flows 1 and 3 to Flow 2 – M2 and M3 are negative
Situation 3: Splitting of Flow 1 into Flows 2 and 3 – M2 is negative, M3 is positive
