How to create qualitative fuel from water and coal: case study
What is “coal-water fuel”? Coal-water fuel (CWSF or CWS or CWF) is a fuel which consists of fine dispersed coal particles, water and plasticizing agent. This type of fuel is widely used as an alternative to gas and black oil on different heat generating facilities. The operational economy is the main of advantages of the coal-water fuel. CW fuel has almost the same heat ...

Inquiry Into Coal Seam Gas
Poorly planned or managed coal seam gas (CSG) exploration or extraction activities pose considerable risks to both groundwater and surface water systems. Key water quality issues, from my own perspective, are listed below. Specific issues may be of greater or lesser significance for particular projects, but all of these issues should be thoroughly and transparently assessed for all proposed ...

Majority of China’s proposed coal-fired power plants located in water-stressed regions
To maintain its economic growth and provide for its massive population, China must reconcile two powerful, converging trends: energy demand and resource scarcity. One prime example of this tension is the country’s coal use and water supply. According to a new WRI analysis, more than half of China’s proposed coal-fired power plants are slated to be built in areas of high or extremely ...

Disposal of saline wastewater from electrical power plants
Saline wastewater from a coal-fired Utah Power Plant has been applied in central Utah, USA, since 1987, to irrigate various agricultural crops. The primary goals of this research: to dispose of saline wastewater by maximising actual evapotranspiration (ETa) and to prevent contamination of surface and groundwater by eliminating runoff and throughout the years (1987-2005). Plots were established ...

Comparison of Gas and Water Pycnometry of Coal Mine Wastes
Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of coal mine wastes is determined more rapidly and efficiently by gas pycnometry than by water pycnometry. However, the two methods give significantly ...

Natural radionuclides in waste water discharged from coal-fired power plants in Serbia
Investigation of the natural radioactivity levels in water around power plants, as well as in plants, coal, ash, slag and soil, and to assess the associated radiation hazard is becoming an emerging and interesting topic. This paper is focused on the results of the radioactivity analysis in waste water samples from five coal-fired power plants in Serbia (Nikola Tesla A, Nikola Tesla B, ...

Dazed and Confused: Alternative fuels and the CISWI definitions rule
As discussed in ALL4’s December 2008 issue of 4 The Record, the use of alternative and non-traditional fuels for heat and power generation is on the rise, an increase that can be attributed to the price surge and volatility of traditional fossil fuels, as well as to a general desire to use more environmentally friendly materials to reduce greenhouse gas emissions. Alternative fuels have been ...

Use of reconstituted waters to evaluate effects of elevated major ions associated with mountaintop coal mining on freshwater invertebrates
In previous laboratory chronic 7‐d toxicity tests conducted with the cladoceran Ceriodaphnia dubia, surface waters collected from Appalachian sites impacted by coal mining have shown toxic effects associated with elevated total dissolved solids (TDS). The objective of the present study was to evaluate the effects of elevated major ions in chronic laboratory tests with C. dubia (7‐d exposure), ...

Water’s Critical Role in the Power Generation Industry
Water and power are intimately connected in the U.S. and around the world. In 2015, electric power generation was responsible for 41% of total water withdrawals in the United States, according to the U.S. Geological Survey. Where does all that water go and what role does it play in power generation? HOW POTABLE WATER IS USED IN POWER GENERATIONELECTRICITY GENERATION Approximately 90% of ...

Wind Surpasses Nuclear in China
Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive growth of 80 percent per year. Before the March ...
