Abstract:

Regarding to the problems of modified dedusting system such as oven wall damage,pipe leakage,high resistance in the dust catcher,this paper analyzes the reason to those problems considering the process principle and equipment condition of de-dusting system.The problems are well solved by changing process parameters of coal preparation,replacing refractories and increasing the pressure of compressed air in the dedusting system,so that normal operation of the dedusting system is ensured.
