Charcoal Tower is a long vertical cylindrical shaped rigid structure which is one of the important element of the combustion system. It is used to spread the flue gases over the wide area at extreme heights to decrease the concentration of pollutants at the ground level. It helps to reduce the air pollution to comply with governmental control regulations. The flue gases generated by the burning of the fuels such as wood, coal, oil, natural gas and many other is combusted in a furnace or boiler enters the charcoal tower. The inner surface is provided with a lining of activated carbon which increases the surface area and the rate of adsorption or chemical reactions with the pollutants present inside the air.
