Spontaneous Combustion of Coal - Practical Maintenance

The first stage is the adsorption and chemisorption of oxygen. During this stage, the coal increases in weight as the oxygen is adsorbed and heat is generated. This process occurs markedly up to 70°C and continues up to 350°C. However, the oxygen-enriched adsorption complex is unstable, and it may decompose and react further.
