Abstract

Abstract: This paper takes a 1 000 MW ultra-supercritical coal-fired boiler as the research object, uses its historical operation data to analyze the sensitivity of the soot blower of the thermal power units based on data mining. The results show that there are different degrees of soot blower sensitivity difference on each heating surface. Based on the sensitivity analysis, the corresponding soot blowing strategies are optimized for different heating surfaces, which is helpful to improve the efficiency and economy of the units.

Key words: coal-fired boiler, data mining, soot blowing optimization, sensitivity analysis
