Abstract. Factors governing behaviour of minor amounts of Cl, K, Na and S in cement production kilns are reviewed. Recirculating loads form as a result of partial volatilisation in the burning zone and are often implicated in formation of build-ups, coating and blockages in cooler parts of the process. Differences arise between plants from ...
