✦ Synopsis

A theory for the thermal ignition of a fuel droplet in a hot oxidizing atmosphere is formulated using an existing gas-phase ignition criterion and an analysis for the transient droplet heating process. Limits on the ignitability of a system, either spontaneous or delayed, are identified. A kineticaUy controlled ignition regime and a droplet-heating-controlled ignition regime are shown to exist in cold and hot environments respectively, each exhibiting distinctively different ignition characteristics. Theoretical results yield reasonable agreement with existing experimental data.

A single suspended-droplet technique has been used to study droplet combustion of a range of solvent-refined coal extracts in a furnace at 850Β°C. The small particles of extract are solid at room temperature but they rapidly liquefy on exposure to the hot furnace environment, permitting the size and
