Energy Consumption Analysis of Pulverizing System in Coal-Fired Power Plant
Pulverizing system is the main energy-consumption equipment in coal-fired power plant, so it is of great significance to study energy-saving and optimization of pulverizing system. This paper first analyzes the situation and condition of pulverizing system in large-scale coal-fired power plant in China. According to analysis, coal mill and primary-air fan are the two Pulverized Coal-Fired Boilers. Pulverized coal firing ensures complete combustion of coal, thus ensuring higher efficiency of steam generators. It is predominantly adopted in large coal-fired utility boilers. The finer the grinding of coal, the more efficient its combustion. The total time required from entry of a coal particle to a furnace toChapter 4. Pulverized Coal-Fired Boilers Thermal Power Plant
