Book excerpt: 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.
