Abstract
DAVIES1 has studied the thermal decomposition of a bituminous coal, and has laid particular emphasis on the heat flux to the coal particles. Individual spheres of coal were suspended from a recording balance in a stream of hot nitrogen. To begin with, the weight record showed a constant rate of loss and in the final part the rate of weight loss decreased with time. The initial constant rate of weight loss was found to be directly proportional to the heat flux and was zero at about 400° C.
