A Study of Coal Selection for a Coal Fired Power Plant Considering Coal Property and Combustion Efficiency

Abstract

In this paper, coal selection for a coal fired boiler in a thermal power station is investigated. Available data of actual used coal types are too small compared with properties of coal type. Classification of coal properties is, hence, introduced and the coal properties are consolidated into several categories through the factor analysis. Since applicability of coal is evaluated by using the multiple regression analysis where the explanatory variables are the factor scores for respective categories. The proposed selection method is applied to a boiler in a thermal power plant.
