Indirect fired rotary kiln elongation

INDIRECT-FIRED KILNS While direct-fired kilns offer an efficient processing option, this method of processing is not always appropriate. An indirect- fired kiln is enclosed in a furnace, which is then heated externally (as shown in the diagram above). This avoids contact between the combustion gases and the material to be processed

    Indirect Fired Rotary Kiln Applications Part 3

    Indirect fired rotary kilns can be beneficial when the material to be processed consists of finely divided solids. 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 discrete particles through form drag. The degree of entrainment depends on a
