Analysis of secondary fuels in use at cement plants

摘要

Secondary fuels employed at cement plants can be composed of very inho-mogeneous materials, including diverse types of polymers, paper, wood and even small amounts of metal. Recycled wood and parts of discarded vehicle tires also find use as secondary fuels. However, before a fuel can be used in the production of cement, a number of quality control analyses must be performed. These include determination of each such material's calorific value, chlorine content and total amount of organic carbon.
