Paul Breeze in CoalFired Generation 2015 Coal combustion is a dirty process releasing a range of pollutants including sulphur dioxide nitrogen oxides carbon dioxide volatile organic compounds ash and a range of heavy metals If these are not controlled they can enter the atmosphere causing damage to the environment and to human health4595
Heres how the process works 1 Heat is created Before the coal is burned it is pulverized to the fineness of talcum powder It is then mixed with hot air and blown into the firebox of the boiler Burning in suspension the coalair mixture provides the most complete combustion and maximum heat possible 2 Water turns to steam3330
