AB - This chapter presents small-scale experiments in which the burning and suppression behavior of smoldering coal are studied. The advantage of reducing the scale and the scope of the problem by studying suppression in the laboratory is that most of the complexities of in-situ experiments such as locating and mapping the fire and the delivery of the suppression agent to the fire seat are eliminated. Meanwhile, the important variables such as fire size, particle size, thermal, and flow conditions can be controlled. The smolder reaction was characterized by maximum temperatures of 700-1000°C, which were seen to be independent of particle size for particle larger than 15 mm. Time to ignition showed a minimum for particles around 30 mm in diameter, with larger particles requiring longer times due to limited heat transfer from the igniter to the fuel. Smaller particles were limited by oxygen transport through the coal. Water was identified as an effective extinguishing agent and was used in small-scale tests. The extinguishing of subsurface fires is dictated by the ability of the delivery method to reach the source of the fire. It was shown that in small-scale tests, significant differences in extinguishing efficiency can arise due to the nature of the extinguishing-agent application. Additional work is required to determine the effects of scale on the reaction. Especially important is determining a relationship, which will allow the extrapolation of data from small-scale experiments to applications involving subsurface coal fires in the field.
