Pigments are manufactured by calcining an intimate mixture of metal oxides at temperatures from 800[degrees] C to 1300[degrees]C. With the kiln being heated with two different fuels--producer gas and oil--it is critical to identify the impact of each fuel on the calcining process. In operation: The sand feeds into the calcining chamber and is elevated to a temperature of 1300F (704C) using an indirect firing method that allows for lower operating temperatures. |
