Coal blending in its simplest form is the mixing of available coals to produce a blend which combusts well to produce heat and/or power. In the past, the focus for plant operators was largely on blending the maximum amount of the cheapest and/or most readily available coals with the minimum amount of .

MW boiler unit. The support vector machine (SVM) is used to establish the pollutant formation prediction model for the coal–fired boiler. Moreover, the model built above is trained and verified based on the actual operation data. Then the genetic algorithm is applied to optimize the coal blending method with the coal price to achieve the lowest

3.1 Introduction and Basic Principles. Blending of alternative coals is the backbone of the fuel blending practice. It is estimated that blends of coals are more commonly combusted or gasified than single coals in commercial applications. It dwarfs the practices of blending coals with biomass or waste-based fuels.

The support vector machine (SVM) is used to establish the pollutant formation prediction model for the coal–fired boiler. Moreover, the model built above is trained and verified based on the actual operation data.
