re how to increase C3S & reduce freelime in clinker. Although you are recording excess oxygen ex-kiln, with a low-volatile fuel such as pet-coke, it is quite likely that - without careful adjustment of burner settings - there may be sufficiently reducing conditions in the burning zone, al least locally, to decompose calcium sulfate, so leading to increased levels of clinker free-lime.
