Abstract
This paper describes the measurement of the autoignition temperatures and ignition delay time for polymethylmethacrylate particles as a function of paticle size and concentration in the Bureau of Mines 1.2-L furnace. Calculations are presented indicating that the kinetics of the gas phase combustion reactions are rate limiting except for the largest particles studied. For the latter, the delay is due primarily to heat-up time of particles. Measurements on the ignition delay times for preheated and unheated liquid polymethylmethacrylate strongly support the limiting gas phase kinetics model.
