RELIABLE, EFFICIENT VACUUM PUMP SYSTEMS FOR THE POWER INDUSTRY CONDENSER HOLDING Improve your condenser vacuum by a half-inch of mercury (0.5"HgA) and see what it could save Each plant has diffrent operating characteristics, but calculating the answer is simply a matter of gathering some data and multiplying. 1. In your "Turbine Data File" there should be a graph or table that shows Turbine Efficiency Improvement as a function of turbine back pressure [condenser absolute pressure]. We recently saw one that indicated a 0.3% improvement if the back pressure were dropped from 2.5"HgAto 2.0"HgA. 2. Dtermine the Turbine Heat Rate, which is the Btu input to the turbine required to produce a kilowatt of electricity. A typical value is about 8500Btu/kW. 3. Dtermine the costof fuel. A rcent spot price for natural gas was $ 7.00 per million Btu's. Use the following calculation: [0.003] [8500 Btu / kW-hr] [$7.00 /106 Btu] =I.SxIO^S/kW This appears to be insignifiant until we factor in the amount of power produced over an entire year. If the plant is rated at 500 MegaWatts (500,000 kW) and it op驩rtes 8000 hours per year: [1.8 x 10" $ / kW] [5 x 10skW] [8 x 10* hr] = $ 714,000 per year* Now that's a figure worth considering! A fraction of this will purchase a condenser-exhauster system. *AII of this, however, dpends on the conditions at your particular plant. Use the above formula to calculate your own potential savings.
