摘　　要：蓄热式燃烧技术是一种全新的节能环保燃烧技术,而换向控制是蓄热式燃烧技术最关键的部分,不仅关系到节能效果,还关系到换向阀和蓄热体的使用寿命。本文提出了一种新型换向控制方式,即预估换向控制系统,该系统根据前期采集的数据,采用牛顿插值法超前预估烧嘴排烟温度,并结合定时换向、预估强制换向和超温强制换向3种换向控制方式,有效防止了换向阀及蓄热体温度超高,延长了换向阀和蓄热体的使用寿命。HTAC technique is a new combustion technique that is advantageous to energy saving and environment protection. Changeover control is the most critical part in HTAC technique because it concerns effect of energy saving and use life of changeover valve and accumulator. A new changeover control mode,i e, estimation changeover control system, is presented. Based on previous collecting data and by use of Newton interpolation polynomial method, the system estimates exhaust smoke temperature of nozzle. And, combining three changeover control modes （timing changeover, estimation forcing changeover and supertemperature forcing changeover）, it effectively avoids that temperatures of changeover valve and accumulator exceed the limit, so their use life is extended.
