Energy-Saving and Optimization of Pulverizing System in Coal-Fired Power Plant

Article Preview

Pulverizing system is the main energy-consumption equipment in coal-fired power plant. In China, coal-fired power plants are obliged to alter operation condition in response to the frequent change of unit load and coal quality, which results in non-standard operation condition and extra energy consumption of pulverization system in consequence. Hence it is of great significance to study energy-saving and optimization of pulverizing system. This paper first analyzes the influence factors on energy consumption of pulverizing system respectively according to literature survey. Due to the large numbers of influence parameters and their complex interactions, these parameters are certain to influence power consumption synergistically in the form of dynamic non-linear variation. This paper groups and defines these parameters into three categories, namely external parameters, constrained parameters, and controlled parameters. Based on the definition, the general model considering all the three groups of parameters is proposed, which considers all the influence factors for energy consumption under all unit conditions. Subsequently, the energy-saving and optimization proposal for the pulverizing system are proposed.
