| Abstract |
This report summarizes the work performed on a program to design, fabricate, and evaluate a controller for automatically sensing and maintaining isokinetic conditions at the inlet of a particulate sampling nozzle. The key components developed on the program were the gas velocity sensor and a fluidic control amplifier. The sensor concept is based on a static pressure differential between the free air stream and the nozzle inlet. The fluidic control amplifier which interfaces directly with the sensor provides the control to automatically maintain isokinetic conditions. Field tests were performed on the engineering prototype system at both oil-fired and coal-fired power plant installations. Results of these tests showed that the sensor and controller can function with no degradation in performance under the adverse environment of representative power plant stacks. |
