  • Combustion of large solid fuels in cement rotary kilns

    Thus, heat transfer by conduction from the cement raw materials to the fuel particles is a major heat transfer mechanism rather than convection or radiation from the freeboard gas above the material bed. Consequently, the temperature of the cement raw materials becomes a factor of great importance for heating the fuel particles.

    Re: Kiln Speed. Volume loading should be typically 78% for precalciner kilns and is higher for preheater kiln. Higher rotation speed increase heat transfer to the charge because the surface of clinker charge exposed to the radiation of the flame and the surface in contact with (hot) refractory is higher compared to the clinker volume.
