The Use of Hollow Plastic Balls as Energy Conservation Devices in Heated Open Tanks
The problem of heat losses from open liquid filled tanks is as old as industry itself. This paper will present the advantages of using an insulating blanket of hollow plastic spheres as a mechanism to conserve this type of industrial energy loss. FIRST: The theory of a floating ball blanket will be covered. Claims on the effectiveness of a ball blanket will be substantiated by results obtained from independent testing laboratories. Slides and graphs of these results, as well as photographs of industrial applications will be presented. NEXT: Attention will be given to specific industries in which open tank energy loss is common. Metal finishing, chemical manufacturing, power generation, sewage/wastewater, and food manufacturing will be highlighted. Other benefits obtainable from floating ball blankets, such as evaporation control and odor control will be briefly discussed. Questions and answers of specific interest from conference attendees will be answered following the presentation. Various methods are available to industry to reduce open tank heating losses. I will present information on the use of an insulating blanket of floating balls to conserve on these open tank heating losses. Where test results are referred to, please keep in mind that these tests were conducted by Capricorn Chemicals Corporation on ALLPLAS type floating ball blankets. ALLPLAS balls are patented by Capricorn Chemicals Corporation.
