CO2 as an Inert Gas. The burning is buried in the mass of coal. It is very difficult to get water to this type of fire. CO2 vapor can be introduced, forced between the voids of the coal to the burning mass and, by eliminating the oxygen, reduce the burning rate until the mass slowly cools and the fire controlled.
