    In a direct-fired rotary kiln, the heat source is hot gas (products of combustion and air), which flows with an inherent velocity. These gases can carry particles through form drag. The degree of entrainment depends on a variety of factors, such as gas velocity, gas density, particle density, and shape

    Aug 31, 2016 · DIRECT-FIRED KILN 8. Direct-fired kilns rely on direct contact between the material and process gas to process the material. 9. Combustion gas is pushed through the drum in either a co-current or counter-current fashion, efficiently processing the material inside the drum. 10. The main advantage to the direct-fired kiln is that it is highly efficient. 11

    Dec 26, 2019 · Rotary kiln can be either of the direct-fired type, or the indirect-fired type. In a direct-fired kiln, a fuel is burnt in the drum, and the material is processed through direct contact with the flue gas. In an indirect-fired kiln, material is processed in an inert environment, and is heated through contact with the shell of the kiln, which is heated from the outside to maintain an inert environment
