Cement Energy and Environment

temperature salts. However, the formation of FeCb by reaction between chlorine and iron fan blades can be ruled out since such a peak (i.e. 306°C, indicating presence of iron chloride) is not evident in the thermal characteristics of fan deposition sample. In the light of above information regarding nature of the deposition characteristics an attempt was made to take corrective actions such as reduction in fan inlet temperatures for reducing fine particulate plastic deformation tendencies & thermophoretic deposition, improvement in top stage cyclone separators efficiencies for reduced dust cycles, stricter monitoring of kiln parameters for avoiding instances of reducing conditions, reduction in deposition frequencies using sonic horns, etc to reduce cleaning frequency of the preheater fan.
