Preheat Towers - HarbisonWalker International

50 rows · Preheat Towers. Kiln preheater towers provide heat transfer from hot gases to kiln feed material. The counterflow of gases and material takes place in cyclones, referred to as stages, in the preheat tower. As material flows from the top to bottom of the tower, it is exposed to increasingly higher temperatures as it is prepared to enter the kiln. Temperatures range from 300°C to 1300°C, with …
