摘要： The invention is directed towards methods and compositions for treating piles of low-rank coal to inhibit its spontaneous combustion. The method involves applying to the low-rank coal a composition containing VAE and crude glycerin. The composition prevents water from evaporating out of the low-rank coal. This prevents the formation within the low-rank coal of hollow openings which are a huge factor in causing its spontaneous combustion. The composition has better performance than its ingredients do alone. In fact it is so effective that certain cumbersome low-rank coal-handling methods, such as FIFO recordkeeping and inventorying, not using pinch points, or only using elbow-free equipment can be disregarded when the composition is used.
摘要翻译：本发明涉及用于处理低级煤堆以抑制其自燃的方法和组合物。该方法涉及向低等级煤应用含有VAE和粗甘油的组合物。该组合物防止水从低等级煤中蒸发掉。这防止了中空开口的低等级煤中的形成，这是引起其自燃的重要因素。该组合物的成分比单独使用的成分具有更好的性能。事实上，使用组合物时，某些繁琐的低等级煤处理方法（如FIFO记录保存和库存）不使用夹点或仅使用无弯管设备是非常有效的。
