Quality based process engineered fuel concept

Abstract

Optimization of TSR in cement kilns can be achieved by using a high quality and consistent alternative fuel product. This case study indicates how a rigorous QC based approach to the production of solid alternative fuels in cement kilns was developed that contributes to maximum TSR. PEF differs from conventional solid alternative fuels in that production begins with the best material possible as the main feedstock and then selected industrial and commercial by-products of known and consistent composition are added to improve the overall mix and thus achieve the desired quality specifications. The PEF concept allows for maximum thermal substitution rates at either a main burner or in a calciner because the product is matched to the specific cement kiln needs and limits.
