  • Indirect-fired Rotary Kiln Design Alpha Thermal Process

    Indirect-fired Rotary Kiln Design Indirect-fired kilns are unusually important where direct-fired operation cannot be employed due to controlled heating, product contamination, etc. These challenges respond to niche applications of unusually high value. Typical Gas-fired Indirect Rotary KilnROTARY KILNS Thomasnet,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.
