Coal Combustion | SpringerLink
Coal combustion is a multistage process. If we focus on the changes in the coal, the process can be described as follows. First, the coal particles are heated to above 100 °C by an external source, and water is vaporized from the coal. Second, as the temperature increases further, volatiles are driven from the coal to form coal char.
