Description:
The report gives results of an investigation of water recycle/treatment/reuse alternatives in coal-fired power plants. Five power plants from representative U.S. regions were studied. The major water systems encountered were cooling, ash sluicing, and SO2/particulate scrubbers. Results were used to provide general implementation plans for the various options identified. Computer models were used to identify the degree of recirculation achievable in each water system without forming scale. The effects of makeup water quality and various operating parameters were determined for each water system. Several alternatives for minimizing water requirements and discharges were studied for each plant, and rough cost estimates were made for comparison. An implementation plan is presented for each water system and is divided into phases, including system characterization, alternative evaluation, pilot studies, and full-scale implementation. This volume discusses the recycle/treatment/reuse opportunities for cooling, ash sluicing, and SO2/particulate scrubbing systems as well as combined systems. It also includes the implementation plans.
