Abstract

Circulation ducts connecting gas cyclones provided for dry preheating cement, the gas being charged with powder, are composed of >=3, pref. 4, metal walls lined with refractory material, whereby each wall is curved and the curves are aligned to provide inwardly directed concave surfaces. Settling of dust between the bricks is prevented.
