Dry Ice for Coal Fires

Dry Ice for Coal Fires

The Consolidated Edison Co., of New York, Inc., has been experimenting with dry ice as a medium for extinguishing fires in coal bunkers. Generating stations using large supplies of coal are frequently faced with the problem of fire, which wastes money two ways, by the wastage of coal, and the cost of labor in the extinguishing process.

It is said that the experiments with dry ice indicate that it can be used as a satisfactory and economical means for fighting bunker fires. For the average fire, approximately one pound of dry ice is used for every two to three tons of coal in the bunkers. The dry ice is placed in holes made about three feet deep and then covered with coal. As the dry ice evaporates, the carbon dioxide gas that is released extinguishes the fire.
