摘要
进行了粉体在高固气比下的多系列热效率的理论研究，指出双系列预热器系统是较为理想的高固气比预热器系统。针对预热器级数、漏风系数对双系列热效率的影响展开研究，其规律对新型预热器系统的开发具有指导意义。
The theoratical research on thermal efficiency of powder preheater system under high solid/gas ratio is carried out. The results show that the bi-series preheater system is satisfactory under high solid/gas ratio. The effects of preheater stage and air-leakage coefficient on bi-series thermal efficiency are also researched, its regular patterns are of guide to the development of new type of preheater system.
