Methodology of Investigating Particle Size Distribution of Coal Samples Prepared for Gasification Process

Abstract

The paper concerns the problem of selection of a proper method of measuring coal fuels particle size distribution prepared for ground gasification in various types of reactors. The review of measuring techniques was done together with determining conditions to their application. The coal particle size distribution destined to gasification process was examined in particle size fractions adapted to appropriate gasification technologies. The results of granulometric analyzes were then approximated and evaluated statistically. The application possibilities were found for two standard methods: sieve analysis – for coarse particles of coal being gasified in solid, moving or fluidized bed reactor and laser diffraction – for fine particles of coal being gasified in technologies based on stream reactor.
