tion. The probe does not use water for cooling but heat transfer fluid with boiling point higher than 3C. This enables gas sampling temperature of more than 2C, that is, above the acid dew point of the flue gas. In this way, con-densation of the flue gas is prevented and substantially less condensate is formed, which results in less expendi-ture for cleaning. The subsequent gas analysis then provides information on the combus-tion processes. The results form the data basis for automated burner opera-3.

The addition of grinding aids has become standard practice and has sev eral aims. Additives increase the throughput, improve the energy effi- ciency or influence the quality of the cement. This is achieved by the spe-cific physical properties of the addi- tives, most of which are liquid. They counteract the agglomeration of the cement particles by neutralising electric surface charges and in this way prevent, for example, cement deposits in the mill. The additives are mixed in amounts of between 0.0 percent and 0.2 percent by weight, and this has to be measured very precisely. As many grinding aids (.., gly - cols or glucose syrup) are not conductive, conventiona
