Environmental Control in Animal Shelters Using Power Plant Thermal Effluents¹

ABSTRACT

Waste heat could be used by farmers to provide environmental control for broilers and swine. The amount of waste heat which could be so used is about 1 to 2% of the total available from electric power plants. A proposed system for using waste heat involves conventional pad and fan systems with finned-tube coils mounted downstream of the pads. The potential savings to farmers in fuel and feed costs are significant. However, major problems exist which must be investigated to determine whether incentives exist to develop and implement such systems. These problems include economics, management, marketing, disposal of animal wastes, dispersion of farming units, size of agricultural operation, climate, and seasonality of waste heat demands.

Key Words: waste heat • electric power plants
