Abstract

A demonstration of an advanced water-conserving cooling system for power plants is being tested. The facility condenses 7.5 kg/s of turbine exhaust steam, equivalent to about 10 MW(e). The system uses anhydrous ammonia to transport the reject heat. Ammonia is boiled in the steam condenser, and then condensed by air in the cooling tower. The system has projected total costs of about one-half of those for corresponding commercial systems. Two advanced air-cooled heat exchangers that are being tested use limited amounts of water for supplemental cooling. Water consumption is about one-quarter the amount required for an evaporative cooling system. The objective of the test is to demonstrate performance and operational feasibility under both normal steady-state and transient conditions, and under non-standard conditions. System response will be determined statistically using industrial-grade instrumentation and a computerized data acquisition system. This paper presents pilot and demonstration test results. System design, construction, instrumentation, and operations and testing are also described.
