Measurements of ignition delay times in cornstarch dust-air mixture

Controlling HCCI ignition timing of biogas by direct injection of solid biomass

“…The studied temperature of the reactive gas is 940 K, and the mean size of particles is 15 µm. An approximate polynomial fit was applied to the results of Li et al [55], of the ignition delay time of softwood as a function of particle size for temperature 862 K. Hence, for this temperature, the ignition delay time of softwood (15 microns) can be estimated to 50 ms [56]. For a temperature of 940 K, the delay is estimated to be shorter, and thus, we expect an ignition delay time of a few milliseconds.…”
