Description
Summary:A mathematical model describing the heat and mass transfer processes during storage and ignition of coal stored in the stack, has been proposed. Numerical studies have allowed to determine the composition of gases and temperature profiles in the depth of the stack, depending on the air temperature and cloud cover. It was found that the cloudless hot weather (daytime temperatures of 303 K) within three days the top of the stack is heated to a temperature is its fire.
