General User Input Values Physics Used Displays Example
This module belongs to the "measuring" components. These are characterized by lines, whose connections and are not connected with other components. Their ends accept data from the connected lines. The connecting lines can be compared with the cables of a measuring instrument or of a sensor for measuring a physical value.
This module has two logic lines. Line 1 measures the profit, line 2 the expenditure. A quotient is formed from these two, which, by definition, is the efficiency.
If a fuel line is connected to the measuring line 2, the sensible and the chemically bound heat is considered i.e. it is also a control element (M*NCV)
Apart from the efficiency ETA related to the net calorific value (NCV), the efficiency related to the gross calorific value is now displayed
as result value ETA_GCV too:
ETA_GCV = Q1 / (M2 * (H2 + GCV2))
Moreover, there are now result values for the heat rate related to the net and the gross calorific value:
HR [kJ/kWh] = 3600 * M2 * (H2 + NCV2) / Q1
HR_GCV [kJ/kWh] = 3600 * M2 * (H2 + GCV2) / Q1
HR_GCV [kJ/kWh] = 3600 * M2 * (H2 + GCV2) / Q1
No specifications necessary.
