Coal and lignite regions are on the way to reinvent themselves. In this work, three aspects related reclamation exploitation of these mining areas analyzed, focusing role geotechnical engineering. Firstly, slope stability excavations is examined during water filling practice. Secondly, effect extreme rainfall studied abandoned mines. Finally, potential a waste dump by highway or railroad invest...

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal based power systems, including the KBR Transport Gasifier, a hightemperature, high-pressure syngas filtration system, and a gas cleanup unit. Designed to be at a sufficient scale to test advanced power systems and components in an integrated fashion, the PSDF provides data necessary for commerci...

Continuous steady-state gasification tests were performed, in which mixtures of lignite and solid recovered fuel (SRF) fed to a bench-scale facility at atmospheric pressure, loaded with the bottom product high-temperature Winkler gasifier as fluidized bed material. The O2/fuel steam/fuel ratios varied from 0.3 0.4 0.25 0.35, respectively, effects temperature examined different levels (700, 750,...

Abstract Arbuscular Mycorrhizal Fungi that colonize the roots of plants growing on lands contaminated by heavy metals may influence phytostabilization process reducing translocation to aboveground parts plant. This study aimed evaluate effects soil amendments (lime and lignite) concentration bioavailable form (CaCl 2 extraction) in colonization Lolium perenne when cultivated soil. During experi...

The experimental facility for pressure hydrogasification research was adapted to the pressure of 10 MPa and temperature of 1300 K, which ensured repeatability of results and hydrogen heating to the process temperature. A hydrogasification reaction of chars produced from two rank coals was investigated at temperatures up to 1173 K, pressures up to 8 MPa, and the gas flow rates of 0.5-5 dm(n)(3)/...

To explore increased risk for human Rickettsia spp. infection in Germany, we investigated recreational areas and renatured brown coal surface-mining sites (also used for recreation) for the presence of spotted fever group rickettsiae in ticks. R. raoultii (56.7%), R. slovaca (13.3%), and R. helvetica (>13.4%) were detected in the respective tick species.

In January 2012, the Sierra Club and the Kosovo Institute for Development Policy (INDEP) issued a report entitled Re-evaluating Kosovo’s Least Cost Electricity Option (Sierra Club/INDEP Report). 1 This report evaluated the World Bank’s proposed Kosovo Power Project, as described in the Bank’s December 2011 study, Development and Evaluation of Power Supply Options for Kosovo: A Background Paper ...

A diode laser based in situ absorption spectrometer is presented for the simultaneous detection of CO (1560nm), water (813nm) and the gas temperature within the combustion chamber of a 600MW lignite-fired power-plant. A fractional absorption resolution better than 10 equivalent to a few hundred ppmV CO could be demonstrated with a 30 sec time response. ? 2000 Optical Society of America OCIS cod...

The modification experiment of Inner Mongolia Baiyinhua lignite by hot air at 200 ℃ for 1 h was carried out. Thestructural changes before and after thermal were analyzed infrared spectrum. Theresults show that the moisture oxygen content in are greatly reduced modification, carboncontent calorific value also increased to varying degrees. In process variousoxygen-containing functional groups dif...
