Effects of Environment Temperature and Humidity on Size Distribution of Smolder Microparticles

Abstract

The smoke particle size distribution of cotton rope smoldering fire were measured with DMS500 Fast Particulate Spectrometer under different temperature and humidity. Through the experiments, we prove that the temperature and humidity of environment have a great influence on cotton rope smoldering smoke particle size distribution. Cotton rope smoldering smoke particle size distribution at an elevated temperature will migrate to small size. Nevertheless, the effect of humidity is more complicated that need a more depth research. Additionally, Fire smoke aerosol is a non-steady-state.
