refratechnik lime kiln

Apr 15, 2020 Apr 15, 2020 The refractory for lime kiln is selected according to different kiln shapes and actual use. The kiln types for producing active lime include rotary kiln, shaft kiln. In general, there are cocurrent regenerative double-chamber shaft kiln, double beam shaft kiln and ring sleeve shaft kiln. The lime kiln is mainly composed of kiln body, feeding device, preheater, distribution, burning zone, cooler, ash discharge

    2-2 Lime Kiln Principles And Operations

    The main chemical reaction in a lime kiln is calcining, the conversion of the calcium carbonate (CaCO3) in the lime mud into calcium oxide (CaO) in the kiln product. Energy is required to cause this endothermic reaction to occur, but there are other energy components to the overall energy demand of the kiln as shown in Slide 16

    Modelling and optimization of a rotary kiln direct

    The kiln model is a one-dimensional finite-volume representation of the governing equations for mass and energy conservation, which are approximated by integration over discrete control volumes along the kiln length (i.e. axial slices). The solution of these discrete equations provides the local gas and solids temperatures, and mass fluxes at each
