The document proposes a modified design for a rotary kiln to reduce heat loss from radiation. It calculates that current radiation losses account for 68.89 kcal/kg or 5.27% of total heat output. The modified design uses a double-layer silicon carbide structure with vacuum insulation between layers. Calculations show this design reduces heat loss to 0.0317 kcal/kg, a 99.95% reduction. …
