Abstract

As a key link in coal-fired power plants, the dynamic energy consumption level of the coal handling system directly affects the overall operation efficiency and economy. This paper conducts modeling and analysis of the dynamic energy consumption of the coal handling system based on different coal quality characteristics, and explores the influence mechanism of physical properties of coal such as particle size, humidity, and bulk density on energy consumption during the conveying process. Through the establishment of a multiple regression model and verification with actual operation data, the quantitative relationship between coal quality parameters and energy consumption is revealed, and then targeted energy-saving optimization paths are proposed, providing theoretical support and practical guidance for improving the energy efficiency of the coal handling system.
