Not illustrated. 1910 Excerpt: ...results seem to warrant further trial in this direction. e. By means of a preliminary heating, the low or initial stages of oxidation are effected. These sources of contributory heat being removed, the forms of destructive oxidation are without the essential of a high starting temperature and are therefore inoperative. Whether such preliminary treatment is within the realm of practical or industrial possibility could not, of course, be determined within the scope of these experiments. /. The submerging of coal, it is very evident, will eliminate all of the elements which contribute toward the initial temperatures. As to its industrial practicability, like the conditions under e above, it can best be determined by actual experience. g. Other processes may be suggested by the formulation of the principles involved. Such, for example, would be the distribution throughout the coal of cooling pipes through which a liquid would circulate having a lower temperature than the mass. This would serve to carry away any accumulation of heat and confine the oxidation to the lower stages only. On the contrary the proposition sometimes made to provide circulating passages for the transmission of air currents is of questionable value, since it may result in the contribution of more heat by the added accessibility of oxygen than will be carried away by the movement of the air. APPENDIX APPENDIX Historical Review With Summary Of Opinions The literature upon the spontaneous combustion of coal is widely scattered and difficult of access to a majority of those most directly interested in the topic. In this series of investigations, a considerable amount of time has been spent in assembling these discussions and making synopses of the same. In order that the results of this phase...
