Oxyfuel combustion in rotary kiln lime production
Having lower specific carbon dioxide emissions than G, F at 1.227 ton carbon dioxide per ton product is considered the best case simulated in this work. It is the conclusion that lime production with an oxyfuel process seems feasible but still requires further studies in order to reach a technical application level.
