The hot flue gases from the kiln are used to heat the raw mill system, coal mill system, and raw meal in the kiln. The gasses exit the preheating tower with a temperature of 370 °C. Because the filter bags (pos. 421) cannot withstand temperatures higher than 140 °C, the flue gasses must be cooled at the cooling tower.
