Air Emission Data Summary for Portland Cement

The Portland Cement Association (PCA) has sponsored the compilation of air emission test data obtained at cement kilns firing tire-derived fuels (TDF) such as whole tires and chipped tires Cement kilns provide an excellent environment for TDF combustion due to the extremely high gas temperatures and long gas stream residence times Cement clinker is made by pyroprocessing of kiln feed into the preheater-kiln system The preheater-kiln system consists of a multi-stage cyclone preheater with five stages combustion chamber riser duct rotary kiln and grate cooler
