Long term exposure to high amplitude whole-body vibration is strongly associated with the development of back injury. Mobile plant used at mines are likely to be a source of high vibration amplitudes and management of the hazard requires systematic measurement of vibration levels. This paper describes measurements of whole-body vibration taken during projects funded by the Coal Services Health ...

For example, biomedical research on the carcinogenity of synthetic fuels mixtures is primarily sponsored by the DOE and conducted through its national laboratories, which are viewed by some groups as proponents of synthetic fuel development. Although the technology for producing liquid fuels from coal was first demonstrated by Germany during the 1920's, coal lique-faction is still in an early s...

Some coal seams in southeast BC are characterized by fine size consist and a moderate amount of inherent ash. Mining strategies and wash plants are designed to handle these coals but sometimes seams are mined, that are unusually difficult to clean. Samples of a number of such coals were acquired and studied. Samples come from a mine and an adjacent property ( samples GC in tables) near Sparwood...

Power plant boiler had no arrangement of measure the coal pipe temperature in a continuous basis, though it is an important parameter for any coal fired large boiler. As pulverized coal flows through the long coal-pipe by the help of flow of hot air as a carrier, coal pipe temperature is only the measurement of the coal flow through the pipe to boiler. Low temperature indicates improper flow of...

Benchmarking cleaner production performance is an effective way of pollution control and emission reduction in coal-fired power industry. A benchmarking method using two-stage super-efficiency data envelopment analysis for coal-fired power plants is proposed – firstly, to improve the cleaner production performance of DEA-inefficient or weakly DEA-efficient plants, then to select the benchmark f...

Burning coal to generate electricity is one of the key sources of atmospheric carbon dioxide emissions; so, targeting coal-fired power plants offers one of the easiest ways of reducing global carbon emissions. Given that the world’s largest economies all rely heavily on coal for electricity production, eliminating coal combustion is not an option. Indeed, coal consumption is likely to increase ...

The Wabash River Coal Gasification Repowering Project (WRCGRP), a joint venture between Dynegy Power Corp., and PSI Energy, Inc., began commercial operation in November of 1995. The Project, selected by the United States Department of Energy (DOE) under the Clean Coal Program (Round IV) represents the largest operating coal-gasification combined-cycle plant in the world. This demonstration proj...

More than 50% of electricity in the U.S. is generated by coal. The U.S. has large coal resources, the cheapest fuel in most areas. Coal fired power plants are likely to continue to provide much of U.S. electricity. However, the type of power plant that should be built is unclear. Technology can reduce pollutant discharges and capture and sequester the CO2 from coal-fired generation. The U.S. En...

There have been contradictory reports of the relative proportion of mercury from coal-fired power plants that deposits locally. Our objective was to determine any local effect of coal-fired power plants on total mercury concentrations in wetland sediment and tadpole samples. Four power plants and 45 wetlands were selected for study. Total mercury concentrations were determined in 75 sediment sa...

There is uncertainty about the ex-ante returns to research, development, and demonstration programs in the United States on carbon capture and sequestration (CCS) technology. To quantify this uncertainty, we conducted a written expert elicitation of thirteen experts in fossil power and CCS technologies from the government, academia, and the private sector. We asked experts to provide their reco...
