Therefore, an indirect rotary kiln is usually made out of a more temperature-resistant alloy, instead of carbon steel. Conclusion. While direct-fired kilns offer maximum efficiency, they are not always appropriate for the intended process. In settings such as these, an indirect-fired kiln would offer the best processing solution.
