Zpracování modelu technicko-ekonomického hodnocení alternativního paliva při výrobě v tepelných elektrárnách, cementárnách a na aglomeraci železných rud

Abstract

Coal mining and processing in Silesia (Slezsko) has produced a huge amount of coal-water slurry as its by-product; it was, as a rule, deposited at disposal sites. The coal-water slurry is now being re-extracted and re-processed for fuel. This thesis gives account of it being used to produce electricity and, to an extent, in cement production, both as fuel and an additive agent. The theoretical section describes ways of dealing with coal-water slurry used so far and outlines its power supply and cement production potential. The practical section gives a detailed account of the proposed alternative fuel production, including an analysis of its relevant properties. This yielded information which was then used to draft a technical-economic model to explore the alternative fuel production efficiency. The final section seeks to cover potential ways of enhancing the properties of the fuel to extend the application range.
