A calorimetric study of the immersion of bituminous coal in liquids
The surface properties of coal greatly affect its use in industrial processes such as gasification, liquefaction and the use of coal slurries. In addition, such processes also involve reagent penetration into coal pores and the oxidative state of the coal surface. Reagent penetration into coal was …

An investigation into the bioconversion of South African sub-bituminous coal by Trametes species and Trichoderma atroviride
… of the bioconversion of a South African (SA) sub-bituminous coal to produce low molecular mass intermediates which may be used in further processes to yield value-added compounds. Low rank coals (LRC), which are less desirable for combustion processes than high rank coals, are more amenable to …

The arbitration review board: an analysis of its development and impact on the arbitration process in the coal industry
The Arbitration Review Board existed in the bituminous coal industry from 1974 to 1981. Established during the 1974 contract negotiations between the Bituminous Coal Operators Association and the United Mine Workers of America, the ARB represented an effort to obtain consistency in arbitration …

Energy ans exergy analysis of biomass co-firing in pulverized coal power generation
Biomass co-firing with coal exhibits great potential for large scale utilization of biomass energy in the near future. In the present work, energy and exergy analyses are carried out for a co-firing based power generation system to investigate the impacts of biomass cofiring on system performance …

Fuel-NOx Formation during Low-Grade Fuel Combustion in a Swirling-Flow Burner
… use of this renewable fuel in pulverized coal power plants. The current research is aimed to investigate the impact of biomass cofiring on NO formation in the near-burner region through interpretation of computational fluid dynamics (CFD) predictions and data collected from a series of …

Combustion of Coal Dust-Air Mixtures (Flammability, Radiation, Volatile)
Coal dust flammability studies are essential in order to evaluate propagation limit concentrations and the fundamental burning velocity as a function of dust concentration. This work presents such data for Pittsburgh seam bituminous coal dust using a relatively large scale horizontal flammability …

Integrating vitrinite reflectance, rock-eval pyrolysis, flourescence microscopy and palynology of the Athabasca oil sands, Kearl Lake area, northeastern Alberta
… levels equivalent to the rank of lignite to sub-bituminous coal. Although differing lithologies have influenced VR to some extent (i.e., coals and bitumen-rich zones), groundwater influence and oxidation seem not to have measurably altered YR. Rock-Eval analysis points to Type III/IV kerogen, and …

Modeling the Performance and Emissions of British Gas/Lurgi-Based Integrated Gasification Combined Cycle Systems
… fueled with municipal solid waste (MSW) and coal in ASPEN PLUS —C a chemical process simulation software package. The power system modeled is an integrated gasification combined cycle (IGCC) and has several advantages over conventional combustion plants including lower pollutant emissions; …

Mechanisms of Microbial Methane Production from Sub-Bituminous Australian Coal
Biogenic methane production from coal necessarily involves a community of microorganisms acting in concert. The large, lignin-like molecules in coal cannot be metabolised by methanogens and other microorganisms are required to catalyse the breakdown of coal to acetate, hydrogen and carbon dioxide. …

A steam-load study of the Virginia Polytechnic Institute power plant
… The building of a storage place to make dry coal available tor No.4 boiler would release approximately 6,700 pounds per hour of latent steam capacity. Further gains could be made by forcing boilers 1, 2, and 3 to higher ratings with excess air during the peak hours, while the use of a higher …

The effect of particle size distribution on the rheology of ultrafine coal-water slurries
Recent interest in producing superclean coal has lead to the development of coal cleaning techniques which require the grinding of coal to sizes below 10 microns. Coal in this size range has inherent material handling problems, most of which can be eliminated by the utilization of this ultrafine …

The effect of operating conditions on emissions from a two-stage lump coal combustor
Residential coal stoves emit various pollutants such as CO, NO<sub>x</sub>, SO<sub>x</sub>, and smoke. The emissions can be reduced by varying the burning conditions in the stove. This investigation studied the effect of various burning conditions on the emissions from a two-stage lump coal …
