摘　　要：通过对鲁奇炉工况的分析,说明了γ料位计应用于灰锁料位检测存在的不足及难以推广使用的原因,提出了通过在灰锁上安装热电偶,并对检测温度趋势曲线进行分析,确定灰锁料位的方案。当灰锁满时,检测点的温度迅速上升,利用这一特点实现对灰锁料位的确定,并实践证明行之有效。Based on the analysis of the operation conditions of Lurgi gasifiers and due to the disadvantages of γ level detector attached to the ash lock and the difficulties in the popularization of such detectors, the authors put forward a new method to determine the lever of ash lock by detecting the temperature of ash lock with a thermocouple. According to the property of fast temperature increase at the test point when the ash lock is full, the level of the ash lock can be detected effectively by adopting this method.
