Result Interpretation

Boiler Steady-State Energy Balance Closure Error calculator computes Energy balance closure error in kW using the defined engineering formula and the input values provided. Energy balance closure error is expressed in kW. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Fuel chemical energy input = 120000
  • Preheated combustion air sensible heat input = 8500
  • Fuel sensible heat input = 120
  • Steam enthalpy rise (gross) = 98500
  • Flue gas sensible heat loss = 22300
  • Radiation and convection losses = 1250

Expected Result:

  • Energy balance closure error = 6570

Engineering Interpretation:

Under the given input conditions, the calculated result is: Energy balance closure error = 6570 kW.

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

energy balance closure error = (fuel chemical energy input + preheated combustion air sensible heat input + fuel sensible heat input) - (gross + flue gas sensible heat loss + radiation and convection losses)
