Predictions/Analyses

The VEA allows an operator to determine the effects of a potential modification – before spending large sums of money.

This example shows an unmodified plant on natural gas producing 295.7 MMBTU/Hr with an efficiency of 70.6%. Modifying the plant with a heat recovery system, it still produces 296.2 MMBTU/Hr – but at an efficiency of 81.4%!

If 1/3 of the savings are normalized for the year, the savings amount to:

  • Save 360 therms/hour of natural gas
  • $3,150,000 at fuel costs of $1.00 per therm
  • A reduction of 20,200 tons/year CO2
  • Similar NOx and CO reductions
