摘　　要：通过四级、五级和六级预热预分解窑系统节约煤电的比较,阐明了带余热发电的五级预热预分解窑系统的能源利用率高于带余热发电的四级预热预分解窑系统,而六级预热器系统比五级、四级预热器系统节能效果更好。采用六级预热器系统可以适当降低预热器出口废气温度,实现废气热焓的充分回收,从而有效地实现烧成系统的节能减排。By contrasting energy-saving of decomposition kiln system with four-stage, five-stage and six-stage preheater, it clarified that energy efficiency of system with five-stage preheater and waste heat power generation was higher than system with four-stage preheater. The energy-saving effect of six-stage preheater is better than five-stage and four-stage preheater. Six-stage preheater system was appropriate to reduce the outlet exhaust gas temperature of the preheater, while the exhaust gas enthalpy could be fully recycled ,which easily achieved the purpose of the energy-saving and emissions reduction of the firing system.
