The goal of this paper is to compare the amortized cost of electricity from two different types of solar thermal energy technologies with the cost of electricity from a coal-fired power plant utilizing newly developed carbon capture (amine-scrubbing) technology. Coal, natural gas, and nuclear fuels are the dominant sources of electrical energy in the United States. Currently, the primary source...

Coal miners are exposed to a wide range of genotoxic agents that can induce genome damage. In addition, miners are characterised by a high risk of the initiation of different occupational inflammatory as well as non-inflammatory diseases. The aim of this investigation is to analyse the modifying influence of occupational pulmonary inflammatory diseases on the level of chromosome aberrations (CA...

The thermal characteristics and kinetics of coal, biomass (pine sawdust) and their blends were evaluated under combustion conditions using a non-isothermal thermogravimetric method (TGA). Biomass was blended with coal in the range of 5-80 wt.% to evaluate their co-combustion behaviour. No significant interactions were detected between the coal and biomass, since no deviations from their expecte...

The facility is located four miles east of Hayden in Routt County, and consists of two BART-eligible boilers. Unit #1 is rated at 190 MW and is dry-bottom, wall-fired. Unit #2 is rated at 275 MW and is tangentially-fired. The Hayden boilers burn Colorado coal that primarily comes from two different mines in northwestern Colorado, the Twenty Mile Mine and the ColoWyo Mine. Coal characteristics a...

Particle-byparticle scanning electron microscopy (PBPSEM) and scanning electron microscopy point count (SEMPC) are being developed and applied for characterizing the inorganic phases in coal and coal combustion products. PBPSEM sizes, identifies, and quantifies coal mineral constituents and the degree of mineral-coal association. SEMPC determines the chemical composition and abundance of inorga...

Work is focused to the study of unburned carbon in ash from coal (and wastes) combustion in 8 combustion tests at 3 fluidised-bed power station, at co-combustion of coal and wastes (also at fluidized bed) and at bench-scale unit simulating coal combustion in small domestic furnaces. The attention is paid to unburned carbon contents in bottom ashes and fly ashes at these 8 combustion tests and t...

Spectrum technology in coal quality detection has become a research hotspot with the maturing of spectral technology and the continuous development of spectral imager. This article mainly analyzed and summarized the progress and research status of scholars at home and abroad based on the coal quality index (moisture, ash content, volatile matter, fixed carbon and sulfur content).According to th...

Sorption processes can be used to study different characteristics of coal properties, such as gas content (coalbed methane potential of a deposit), gas diffusion, porosity, internal surface area, etc. Coal microstructure (porosity system) is relevant for gas flow behaviour in coal and, consequently, directly influences gas recovery from the coalbed. This paper addresses the determination of coa...
