The Királyegyháza Cement Plant is one of the leading manufacturers of high-quality cement in Hungary, with a yearly capacity of more than 1 million t of cement. Lafarge believes that it can recycle 100 times more waste than produced during its operation. The company’s aim for 2050 is to reach the net zero emission rate.
Flash Dryer for alternative fuels
Reaching high thermal substitution rates (TSR) requires firing of alternative fuels at the kiln burner. To reach a stable sintering zone for the required clinker quality, a high fuel quality (high LCV, small particle size) is needed, otherwise the clinker quality may suffer or the TSR can be limited. With the A TEC Flash Dryer various waste heat sources can be used (clinker cooler flue gas, bypass gas, preheater gas, etc.). The material is dosed to the hot gas flow in the flash dryer and transported with this gas flow, while the moisture is evaporated, to a cyclone and a subsequent filter where the fuel is separated from the gas flow and on-line fed to a kiln burner or a satellite burner. In addition to the drying, the lifting effect of the gas can separate 3D impurities, contributing to a further improvement of the fuel quality.
