β¦ Synopsis
found that, char combustion rate increase with increasing ugQg or ug.o. Combustion rate can be expressed by using the oxygen concentration at standard temperature and pressure, Co, or the partial pressure of oxygen, P02, as the gas reactant term in the rate equation. However, explanation of pressure effect on combustion rate was greatly different in both expressions.
02/02142 Experimental study of burning rate in hydrocarbon pool fires
Chatris, J. M. et al. Combustion and Flame, 2001, 126, (1-2), 1373-1383. Experimental results on hydrocarbon pool fires are reported. Experiments on gasoline and diesel oil pool fires with diameters of 1.5, 3, and 4 m were carried out and burning rate was determined through the measurement of the variation in flue level as the fire proceeded. The instantaneous value of burning rate was thus established as a function of time. This allowed the analysis of the transient periods at the beginning (fire development) and end (fire extinction) of the whole process, as well as the determination of the average burning rate during steady-state fire as a function of pool-fire diameter. The effect of wind speed on burning rate was also studied. Finally, a set of conclusions were drawn from experimental results.

We present a novel experiment to study the ignition of pulverized coal. A dilute stream of particles is dropped into a laminar, upward-flow wind tunnel with a quartz test section. The gas stream is not preheated. A single pulse from a Nd:YAG laser is focused through the tunnel and ignites the fuel.
