Abstract

Abstract: A unit frequently participated in the deep peak load regulation of the power grid. In the process of deep peak load regulation, the time of oil feeding and stabilization of combustion was relatively long, which caused the blocking of the pipeline at the inlet of the ash storage pump at the rear of the electrostatic precipitator. According to the analysis, it was found that it was caused by the spontaneous combustion and coking of mixture of oil and pulverized coal which had not been thoroughly burned in the ash bucket.
