温度检测技术在鲁奇炉灰锁料位检测时的应用

Application of Temperature Detection to the Level of Ash Lock of Lurgi Gasifier

通过对鲁奇炉的工况进行分析 ,说明了γ料位计应用于灰锁存在的一些不足及难以推广使用的原因 ,可在灰锁上安装热电偶 ,对检测温度趋势曲线进行分析 ,当灰锁满时 ,检测点的温度迅速上升 ,利用这一特点可实现对灰锁物位的检测 ,实践证明是可行的。

Based on the analysis of the running conditions of the gasifier, and of the disadvantages in the application of γ level detector to ash lock, the authors put forward a new method to determine the level of ash lock by detecting the temperature of ash lock with a thermocouple according to the fast increase of the temperature of the test point when the ash chamber is full .The result is practicable.
