Effective Utilization of Flue Gas from Titanium Dioxide Production Plant

The calciner uses furnace oil as its fuel. The flue gases coming from the calciner has a high thermal energy. This work is done to effectively utilize the thermal energy produced and hence to reduce the fuel consumption. By utilizing the heat energy of flue gases, the TiO2 slurry can be preheated using a heat exchanger. This preheating can reduce the total amount of the furnace oil used in the combustion chamber. Also by effectively utilizing the remaining heat of the gases using another heat exchanger, the furnace oil can be preheated which in turn eliminates the use of heating coil. Thus the efficiency of the plant can be improved by this technique.
