HOW COOLING TOWERS AFFECT PROCESS ENERGY SAVINGS.

Type of article: Article

Summary

THE AUTHORS SUGGEST THAT COOLING TOWER STUDIES ARE OFTEN NEGLECTED IN THE APPROACH TO ENERGY SAVINGS IN PROCESS PLANTS. THEY SHOW THAT FOR EVERY COOLING TOWER IT IS POSSIBLE TO CONSTRUCT A CHARACTERISTIC CURVE RELATING RANGE, APPROACH AND ENTERING AIR WB TEMPERATURE. COOLING TOWER MANUFACTURERS NORMALLY PRODUCE INFORMATION SHOWING FAN POWER. IF THIS IS ADDED TO KNOWLEDGE OF PLANT ENERGY REQUIREMENT FOR CHANGING COOLING WATER TEMPERATURES, IT IS POSSIBLE TO SEE THE EFFECT OF POWER SAVING FOR WB AIR TEMPERATURE REDUCTION. HOWEVER, MOST PLANTS REACH A POINT WHERE SAVING IN PLANT ENERGY BECOMES LESS THAN COOLING TOWER FAN ENERGY. AT THIS POINT ENERGY SAVING IS POSSIBLE BY REDUCING FAN OPERATION RATHER THAN LOWERING WATER TEMPERATURE. AN EXAMPLE IS GIVEN TO ILLUSTRATE THE METHOD OF INVESTIGATION. D.W.H.
