Two basic homogeneous lithotypes, defined as elementary coal layers, within the seam of lignite can be distinguished: xylitic and detritic coal. As each them exhibits various features, including structure, mechanical, technological properties, chemical ash composition, share lithotypes a deposit provides important information regarding applicability this fuel. This study describes unique three-dimensional reconstruction microstructure using scanning electron microscopy (SEM) to acquire...
Low production costs have contributed to the important role of lignite in energy mixes numerous countries worldwide. High moisture content, though, diminishes applicability power generation. Superheated steam drying is a prospective method raising calorific value this fuel. This study describes numerical model superheated from Belchatow mine Poland two aspects: single and multi-particle. The experimental investigation preceded analysis provided necessary data for preparation verification...
Integrated coal Gasification Combined Cycle (IGCC) is the most advanced technology for coal-fired power generation. The two-stage entrained flow gasification process allows use of a wide range coal, as long temperature above ash melting point used fuel. In this technology, lignite, which often has low point, can be preferably utilized. However, fluidity also another importance, because behaviour molten slag diminish stable discharge from gasifier. As eligibility properties considerable...
A superheated steam fluidized bed dryer (SSFBD) in a self-heat recuperative configuration has great potential of improving thermal efficiency lignite-fired power plant by recovering both latent heat vaporization water kept the fuel and part sensible during processing. However, optimal design requires fundamental knowledge drying characteristics respect to individual properties utilized fuel. Experimental investigation determine correlation between specific coal originated from geological...
Low calorific value of lignite, mostly attributed to high moisture content, undermines usability this low rank coal. Upgrading the quality energy carrier, which benefits coal-fired power plant's thermal efficiency, can be effectively realized by means drying. The kinetics superheated steam drying was studied for 30 mm spherical samples from Belchatow lignite mine in Poland. experiment featured simultaneous and continuous measurements weight temperature. kinetics, described curves rate...
Water removal is a key technology for enhancing efficient utilization of lignite in power generation. An inherent characteristic lignite, attributed to the large amount water kept within fuel, factor decreasing thermal efficiency lignite-fired plants.
