Reducing LSF

13 October 2014, Published under Cement News

Just over a year ago an article in ICR discussed the possibilities for reducing CO 2 emissions from a cement plant. 1 One option was to use less limestone in the kiln feed, thus reducing the CO 2 released by calcination (both by dissociation of CaCO 3 and because most fuel is used in calcination) and making the kiln feed easier to burn in the burning zone (which therefore requires less fuel). But what are the quality implications of such a reduction and how might they be overcome? ...
