Study on Flame Temperature Measurement of Pyrotechnic Composition Using Transient Spectrum Radiometer

摘要

This article analyzes the burning flame characteristics of pyrotechnic composition. As there are radiations in the visible spectrum for luminous flame that contains mote, the flame of pyrotechnic composition is analyzed to be luminous flame. The emissive curves of the combustion of pyrotechnic composition are tested using the transient spectrum radiometer. Through comparing with the emissive characteristics of gray body, the combustion radiation characteristics are classified into three kinds of situation. According to the classification, the temperature measurement of pyrotechnic composition is also discussed in this paper.
