Abstract

Abstract: Blended coal combustion in power plants can effectively reduce the fuel cost, but it may cause volatility of the coal quality for the boiler as well as the quality deviation from the designed coal. It is becoming an increasingly urgent problem to be resolved regarding how to maintain safe and efficient operation of boiler. In this paper, the main bottlenecks of the current boiler combustion, such as pulverization, air distribution, design and manufacturing, are ana-lyzed, and the integrated solutions are proposed in three aspects, which consist of the optimization of fuel input, boiler combustion equipment, and the fine operation control of the combustion process. The key monitoring and optimizing operation technologies for fine control of pulverized coal and fine air distribution in furnace are emphatically studied and discussed. Since boiler combustion optimization is a complex system engineering, the scheme presented in this pa-per provides necessary design guidance and reference for the implementation of combustion optimization engineering in thermal power plants.

Key words: boiler, blended coal combustion, combustion optimization control, advanced combustion monitoring
