Kiln bypass Question 1 - International Cement Review

There is no absolute relationship between chloride content and alkali volatility. This depends on the other anions present and also the burning zone temperature in your kiln. However, it is possible to say that the presence of chloride will increase the volatility of alkalis.

2013-4-19  A new process has been developed for processing chlorine-bypass-dust into new materials that can be sold or used in the cement kiln. Bypass dust is the dust that is rejected from a kiln system in order to lower the chlorine or alkali content of the produced clinker. Many cement plants have routinely landfilled this dust over many years. The strategic concept of "zero waste" is the basis for ...
