Measurements of Emissions Produced by Burning Alternative Fuels in the Cement Industry



For more than 20 years now the cement industry uses alternative fuels and raw materials (AFR) within the cement production process. In particular industrial plastic, solvents or waste wood are used as additives. In order to determine emissions potentially hazardous to the environment resulting from adding alternative fuels the necessity arose for measurements in the kiln system at the stack.


V&F’s Ion Molecule Reaction Mass Spectrometry (IMR-MS) technology is capable of determining inorganic and organic volatile compounds emitted during the process. Alternative fuels typically show only a negligible influence on the stack gas composition with respect to sulphur containing compounds such as SO2, CH4S, COS and C2S, nitrogen containing compounds such as NH3 or N2O or organic compounds.


V&F equipment can be used to monitor stack emissions continuously during cement production. As results are reported immediately potentially hazardous emissions can be suppressed and the production process adapted in a timely manner. Easily manageable calibration routines allow for measurements of absolute concentrations. Depending on the result the process can be altered appropriately by adjusting for the use of alternative fuels.
