Flame Image Pyrometry in Combustion Chamber Temperature Field Measurement

摘要

In order to make up for the defects of traditional temperature measurement methods, CCD cameras are gradually applied to the measurement of temperature fields of high-temperature objects. In this paper, by establishing the furnace flame radiation energy imaging and temperature imaging model, an algorithm for reconstructing the temperature field is proposed, and the feasibility of reconstructing the three-dimensional temperature field of a large furnace chamber is analyzed and demonstrated. On this basis, a breakthrough in real-time visualization and detection technology of the three-dimensional temperature field in the combustion chamber of an aero-engine is realized.
