  1. Salt River Project, Saint Johns, AZ (United States). Coronado Generating Station
This presentation will include Salt River Project`s design, installation, experiences and results using ultrasonic flow monitoring equipment for certification of continuous emissions monitoring systems. Flow Monitoring is the newest and has been the most controversial component of CEM systems. Experience in measuring flue gas volumetric flow prior to CEMs was very limited. There are currently three basic techniques used to measure gas flow: (1) thermal sensing using hotwire anemometer or thermal dispersion; (2) differential pressure (pitot tube and annubar); (3) acoustic using ultrasonic transducers. The Salt River Project (SRP) operates a variety of affected generating stations: coal, gas and oil. Ultrasonic flow monitoring technology was chosen for all affected generating stations which the author operates. SRP`s approach and reasoning for choosing ultrasonic systems will be discussed. A review of each generating station`s flow monitoring system will be presented. The presentation will include, but may not be limited to, the following: general facilities, description and schematics; physical installations, plan and section drawings; design considerations; results of flow monitors certification testing; and CEMs Project Manager`s conclusions.
