Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of utilizing once-through cooling water discharge from large steam-electric power plants for surface irrigation was investigated. Advantages for the power plant include reduced turbine back pressure with greater power output and thermal efficiency, as well as reduced cost and environmental impact, as compared with closed-cycle cooling systems. Crops could benefit from moderately elevated water temperatures of irrigation which tend to increase yield for certain species. As an example, a 2000 MW(e) fossil-fueled plant was analyzed. It was determined that about 178,000 acres would be required under typical optimal average spray-irrigation rates of 1.5 inches/week and the optimal field crop, corn. For this size system, water temperatures would be in near natural equilibrium at the average crop location. Thus no thermal advantage can be claimed for crop growth. Considering the irrigation system investment and return, the net cost of cooling in 1980 dollars was estimated as 4 mills/kWh as compared with 0.7 and 1.7 for wet and dry mechanical-draft towers, respectively. In the case of tomatoes, a net profit of 3 mills/kWh might be achieved assuming that the market could absorb the enormous yield, which is unlikely. During non-irrigation periods, a conventional cooling system, or the irrigation distribution system with a bypass return to the plant or the natural water body would have to be employed at additional cost. The prospects of using hot-water blowdown for more limited surface irrigation appears more practical and may be viable as a system zero-discharge alternative.
