Coal Type Selection for Power Plants Based on Combustibility and Fusibility

Abstract

In this paper, a coal type selection method for a coal fired boiler in a thermal power plant is proposed. Coal combustibility and fly ash fusibility are derived by fuzzy inference using the coal and fly ash properties. Then, combustion state for each coal type is evaluated by the coal combustibility and fly ash fusibility. Applicable coal type is selected by the evaluated combustion state. The proposed coal type selection method is evaluated by the data collected from test furnace and an actual thermal power plant.
