PRELIMINARY ASSESSMENT OF THE USEFULNESS OF THE LIGNITE FROM GUBIN DEPOSIT IN THE GASIFICATION PROCESS
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2012, Vol 448, Issue 448
Abstract
The paper presents the possibility of using lignite from the Gubin deposit in the major types of gasification, including moving bed, fluidised bed and dispersion (entrained flow). Important parameters in the coal gasification process, such as total moisture, ash content, total sulfur content, carbon content and ash melting point, were studied. The results were compared with the requirements for each gasification technology. The coal does not meet the criterion of the maximum moisture content and – in order to be used in the gasification process – its drying is necessary. Lignite from the Gubin deposit meets the criteria of the maximum ash content and minimum melting temperature, specified for the fluidized bed gasification. A preliminary analysis of the quality of coal from the Gubin deposit suggests that it can be used in a ground-based gasification process using fluidized bed.
