Excerpt from Effects of Moisture on the Spontaneous Heating of Stored Coal There is no doubt a floating opinion among people accustomed to the handling of coal to the effect that moisture does increase the tendency to spontaneous combustion. In a letter to the English commission in 1876, Mr. Poole, inspector of mines, Nova Scotia, makes the following remark: Heat has been observed in piles of slack coal that have been accumulated during the winter, when the season has been showery but not when it has been dry. This evidence is very direct and absolutely opposed to Fayol's experience, and a great deal of similar evidence was tendered to the English commission. For instance, out of 26 answers to questions as to the effect of moisture every reply was to the effect that moisture was a source of danger. An examination of the reported evidence shows that in every case (with the above exception) this was a matter of impression merely. Cross-examination of a number of witnesses before the New South Wales commission, who held this opinion, convinced me that it was in general held'on very slender grounds; and two cases in which the rain had apparently increased the tendency of the coal to heat were otherwise explained. In the presence of air and moisture pyrite readily oxidizesc and pyrite in coal has often been blamed for spontaneous combustion. Threlfall d showed that the oxidation of pyrite has much less effect in the heating of coal than the oxidation of the coal substance itself. He reviewed the work of previous investigators and commissions that investigated mine fires all the evidence was against the idea.

Excerpt from Effects of Storage Upon the Properties of Coal It will be seen from this summary that the most serious part of the problem relates to the matter of spontaneous heating, and prob ably the least serious phase relates to deterioration and actual loss of heat values. It is certain that at the present time a better under standing of these difficulties has been reached, and there is reason for believing that this better understanding of the fundamental principles involved will lead to some practicable and safe procedure for the stocking of bituminous coal.

Excerpt from Deterioration and Spontaneous Heating of Coal in Storage: A Preliminary Report Similar views have been held more recently. For example, in a paper before the United States Naval Institute, in 1906, b one finds the statement: The pressure of the weight of coal causes gases to be evolved; these gases constitute the chief and only value of the coal in that they furnish the heat units. It is claimed that if a ton of fine bituminous coal be spread out on a concrete pave ment in the open air in this climate [key West, for one year, it will lose all its calorific properties. The gases are simply free to escape, and when the coal has lost all its gas it will have lost all its heat units and be simply coke. The author's meaning, no doubt, is that the heat units in the volatile part of the coal are all lost by storage in the manner described. In 1907 a German gas-works engineer claimed0 to have found that moist fine coal sustained an average heating value loss of per cent per week by the escape of gas. The 1889 edition of Groves and Thorpe's Chemical Technology of Fuels says: d In some places coal is known to lose 50 per cent of its heating value in six months.

Excerpt from Deterioration in the Heating Value of Coal During Storage The detailed report is presented in this bulletin, which gives a full account of the tests and the analytical data covering a period of five years' storage. Data of somewhat similar experiments for shorter' periods with gas coal from the Pittsburgh bed, with Pocahontas coal on the Isthmus Of Panama, and with Sheridan, Wyo., subbituminous coal, which is used for railroad and other purposes in the West, are included. The tests of New River coal, in cooperation with the Navy Depart ment, were undertaken to determine the advantage to be gained by storing coal under water, and particularly under salt water. Small lots were used in order to make the tests of maximum severity, and parallel experiments were made with run-oi-mine and crushed coal under one-fourth inch size. All of the small lots tested under the different conditions (except those tested near Key West, Fla.) were taken as representative portions from one large original lot.
