  • Alternative fuels in cement manufacturing: Modeling

    The integrated kiln-soil mill-fuel mill system is rigorously modelled. The model, linear in fuel feed flowrates, reveals the kiln balance invariants. The enthalpy balance imposes production cuts under poor alternative fuels (AFs). A five-step procedure leads to noninferior AF mixtures and appropriate manipulation. Air flow or internal fluegas circuiting regulation forestalls undue production cuts.
