Heavy media coal hydro-transport in Malinau, Indonesia: a process study
In Indonesia, coal transportation has traditionally been handled by trucks and by other mechanical means. With the expansion plan of coal production and increasing truck costs, Kayan Putra Utama Coal believes that alternative modes of transportation must be considered. For long distance transport of export size coal, one of the most viable options is to use coal slurry pipeline. This paper ...

Coal is king in China
1.4 Billion Chinese consumers are each day improving their standard of living. This new Ch;ina population is certainly deserving of all Creature Comforts like air conditioning, refrigerators, PC’s – these appliances are stretching China’s energy resources. Many Environmental Experts rightfully worry that China’s energy needs will have to rely on Coal for the unforeseen ...

Coal sorption characteristics and coal surface tension
Underground coal mining in the Bulli Seam of Sydney Basin, Australia encounters the problems of coal and gas outburst as the coal contains high concentration of CO 2 , where certain parts of the seam have been found to be especially hard-to-drain. In order to better understand these problems, the influence of temperature and moisture on sorption capacity of bituminous coal was investigated at ...

Influence and control of coal facies on physical properties of the coal reservoirs in Western Guizhou and Eastern Yunnan, China
Western Guizhou and Eastern Yunnan have abundant coal resources, and they are considered as the most prospective areas for coalbed methane (CBM) development in Southern China. To explore the potential of CBM production in these areas, this paper identifies the plane distribution of coal facies, and analyses its control on the physical properties of coal reservoirs. Four types of coal facies ...

The structural break and elasticity of coal demand in China: empirical findings from 1980-2006
Coal is the principal primary energy source in China. Research on coal demand is vital for informing China's economic development. In this paper, the theoretical structural break of coal demand was tested using annual time series data from 1980 to 2006. Results indicate that coal demand underwent an intercept structural break during the period 1997-2000 (from −0.536 breaking to −0.702). Then ...

Present status and future prospect of clean coal technology in China
Coal consumption accounts for about two thirds of the primary energy consumption in China. High economic growth has brought about a rapid increase of coal consumption. Low-efficiency combustion of a large amount of coal caused coal-smoke related air pollution. The Chinese government put forward plans to develop clean coal technology in the early 1990s, and has listed it as one of the emphases for ...

Experimental studies on hydrophobic flocculation of coal fines in aqueous solutions and flotation of flocculated coal
Hydrophobic flocculation of fine bituminous coal particles in aqueous solutions under mechanical conditioning and without any surfactants has been experimentally studied through the measurements of aggregative efficiency, zeta potential and contact angle in this work. The results have shown that the hydrophobic coal fines strongly aggregated in a wide pH range (3.5?9.5), even though the particle ...

Low-volatile coal combustion technologies in Vietnam: issues and strategies
Vietnam has planned to install a number of coal-fired power plants with unit's capacity of up to 600 MW. Present experience shows that available low volatile anthracite coal is difficult to burn in the PC fired boilers. In this paper, the CFB combustion technology is proposed based on the experiences of coal-fired power plants around the world used similar coal characteristics. Later, a ...

The international coal industry: comments on the paper by David Humphreys and Keith Welham
This comment discusses in more detail one of the primary messages in the paper by David Humphreys and Keith Welham, namely the fundamental shift in the steam coal industry away from security of supply concerns and national focuses towards an international and cost-driven perspective. On the supply side, this has meant an increased focus on mining productivity. By consulting recent research, this ...
