Thermal efficiency analysis of the rotary kiln based on the wear of the lining

The thickness of the lining is reduced from 230 mm to 80 due long-term wear, resulting in low thermal efficiency rotary kiln. resistance, which positively correlated with lining, one most important factors determining kiln can be improved by introducing insulation material lower conductivity into lining. average heat flux used as evaluation index 4×60 m under no-load conditions this work. A numerical experiment was conducted for temperature and inner surface well outer shell during wear There are two cases considered, without materials According analysis, when high zone wears mm, increases 105.03%. However, after addition material, on 40.38% (wears mm). Compared 36.36% (230 mm), it 99.01% significant advantage solution that increase kiln, improve performance reduce loss environment through shell, results obtained latest equipment design existing improvements.
