In this study, a circulating fluidized bed (CFB) of 125 mm diameter and 1800mm height was used to find the combustion characteristics of sewage sludge (SS) produced in Turkey. Sludge + olive cake, and sludge + lignite coal mixtures were burned separately. Various sludge-to-lignite coal and sludge-to-olive cake ratios (5/95, 10/90, 15/85, 20/80) were tried. On-line concentrations of major compon...

The mollusc fauna from the Pliocene Viviparus beds of Vukomeričke Gorice hills in central Croatia was investigated at four sites in the region of Kravarsko, S of Zagreb. The region represents a Pleistocene horst-anticline at the southern margin of the Sava depression. Sediments are dominated by clay, bearing some sand, gravel and lignite intercalations. The molluscs, comprising 11 gastropod and...

Sedimentary Rocks composing the Thar Lignite basin Pakistan are of clastic origin. These rocks have comparatively low uniaxial compressive strength (UCS) values, and hence recognized as ‘soft sedimentary rocks’ in this study. UCS is a fundamental property rocks, used by mine design engineers designing surface underground excavations. The purpose study to investigate relationship between with Br...

Future investment feasibility studies concerning post-mining repurposing utilities and economic transitions should focus on regional water resource management the hydraulic protection of any utilities. Satellite images in different bands Digital Elevation Models (DEM) Ptolemais basin were processed, leading to a more accurate estimation runoff ratio percolation ratio. Furthermore, saturated uns...

The long-term survival of Rhizobium phaseoli strains 127K17, 127K26, and 127K35 in legume inoculants prepared with eight different coals (one strain and one coal per inoculant) was studied. The coals used were Pennsylvania anthracite, bituminous coals from Illinois, Pennsylvania, and Utah, lignite from North Dakota and Texas, and subbituminous coals from New Mexico and Wyoming; they ranged in p...
