• CFD modeling of MPS coal mill with moisture evaporation

    May 01 2010 · It is a common experience that mill outlet pipes have unequal coal flow in each pipe and contain some coarse particles. Unequal coal flow translates into unequal air-to-fuel ratio in the burner deviating from the design value and thus increasing unburned carbon in fly ash NO x and CO. Coarser particles at the mill outlet originate from poor
