| Popis: | A power plant simulator was designed and built for development and calibration of optical diagnostics in power plant flows. This article describes the important features of this simulator as well as it performance. The simulator was constructed using a 120-mm-i.d., approximately 3-m-long quartz tube enclosed in a custom manufactured multizone furnace. Simulation of power plant flows requires combustion effluent; this is provided by a propane burner. Additional gases may be seeded into the flow using ports positioned before the entry into the 3 m quartz tube. Thus, flow with specified concentrations of pollutants of interest (i.e., NO, NH3, SO2, etc.) can be produced. Temperature control for the gas flow entering the quartz tube is provided by a 4-m-long heat exchanger positioned between the burner and the 3-m-long quartz tube. Optical access is provided at the tube ends using NaCl windows, which were chosen for their transmissive characteristics in the visible and infrared. These windows are protected the... |
