A new high-irradiation ignition test and diagnosis method of solid combustibles
THERMAL SCIENCE(2023)
Abstract
This study proposes a new high-irradiation ignition test method for studying the pyrolysis and ignition of solid combustibles under extreme scenarios (> 0.1 MW/m2). The irradiation system that generates a 10 cm octagonal spot of dynamic irradiation with a peak flux of 1.25 MW/m2 and 95% uniformity, and a chamber with wellcontrolled ambient conditions and advanced diagnostics coupled with a multiphysical parameter measurement system. A verification test was conducted on corrugated cardboard using the proposed test method, resulting in high-quality outcomes 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 development of advanced models of material pyrolysis and ignition processes under high irradiation.
