Ignition of coal dust--methane--air mixtures by hot-turbulent-gas jets

Technical Report ·
OSTI ID:5325674

Report presents the results of an investigation of the ignition of hybrid coal dust-methane-air mixtures by hot-turbulent-pulsed-gas jets generated by explosions in a primary chamber of stoichiometric mixtures of methane, oxygen, and nitrogen. This paper reports that ignitibility was influenced by the dimension of communicating channel between a primary explosion and a hybrid mixture, coal-dust particle size in the hybrid mixture, addition of inhibitor to the hybrid mixture, temperature of hot igniting jet, and concentration of methane and coal dust.
