Worked Example

Verified calculation

Given:

  • Specific Heat of Flue Gas = 1.28
  • Stack Gas Temperature = 473.15
  • Ambient Air Temperature = 298.15
  • Higher Heating Value of Fuel = 45000

Expected Result:

  • Stack Loss = 0.49777777777778

Engineering Interpretation:

Under the given input conditions, the calculated result is: Stack Loss = 0.49777777777778 %.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method
