Abstract

This study proposes a new high-irradiation ignition test method for studying the py-rolysis and ignition of solid combustibles under extreme scenarios (> 0.1 MW/m²). The irradiation system that generates a 10 cm octagonal spot of dynamic irradia-tion with a peak flux of 1.25 MW/m² and 95% uniformity, and a chamber with well-controlled ambient conditions and advanced diagnostics coupled with a multi-physical parameter measurement system. A verification test was conducted on cor-rugated cardboard using the proposed test method, resulting in high-quality out-comes with lower coefficients of variation compared to previous test methods. This improved approach provides a better procedure for testing and understanding the ignition threshold of combustible materials and laying the foundation for the de-velopment of advanced models of material pyrolysis and ignition processes under high irradiation.
