- Narrow angle radiometers are being used for forest fire and combustion applications. Generating accurate radiative flux data from these instruments is essential to build flame models and predict fire behavior. Further investigation of current radiometers has revealed a level of uncertainty in measurements that stem from design flaws, calculation error, and lack of information. Main design issues deal with the narrow probe, focusing device, field of view, and sensor. Available information on narrow angle radiometer instrumentation is highly limited. To address this issue, our group is developing a narrow angle radiometer which will be applied to high-temperature and pressure oxy-coal flames in Brigham Young Universities Pressurized Oxy-coal Combustor (POC). This presentation will provide a review of radiometer design. Data will be provided to elucidate the impact of environmental conditions on calibration repeatability. In addition an instrument model will be provided that allows the conversion between the quantity of interest (incident radiation) and the quantity measured (electrical signal).
