Coal Industry in China: Evolvement and Prospects
China is the biggest country of coal production and coal consumption in the world (IEA). In 1998, China produced 1250 Mt of raw coal, accounting for 27.5% of total coal production in the world, and holding 71.9% of primary energy in China (SSB). Coal provides 77% of the energy for power generation, 65% of chemical raw material, and more than 50% of commercial civilian energy. The coal industry ...
متن کاملCan geosequestration save the coal industry?
There is archaeological evidence that coal was used in the Bronze Age, 3,000-4,000 years ago, in ancient China and in Roman Britain. But over the millennia, while human and animal labour and wood burning were the principal energy sources, coal played a minor role. In the pre-industrial age, reflected in the novels of Thomas Hardy and the paintings of the Old Masters, energy supply was local and...
متن کاملReal Time Analysis in the Coal Industry
Real time interrogation and analysis of coal makes it possible to quickly respond to changing conditions and efficiently control coal quality closely to meet operational or contractual specifications. Real time measurement systems generally include an online analyzer, an integrated mechanical sampling system for calibration of the analyzer and for collecting shipment or daily contract samples, ...
متن کاملSustainable development and upgrading mode of coal industry in China
It is an emerging realistic problem on how to promote a high level of technology in the coal industry, find new upgrading powers and create new competitive advantages, which are also the core problems to efficient transformation pattern of economic growth for coal industry in the ‘‘twelfth five-year’’ period, involving the key to China’s energy supply and energy security. Through field surveys ...
متن کاملEstimation of coal swelling index based on chemical properties of coal using artificial neural networks
Free swelling index (FSI) is an important parameter for cokeability and combustion of coals. In this research, the effects of chemical properties of coals on the coal free swelling index were studied by artificial neural network methods. The artificial neural networks (ANNs) method was used for 200 datasets to estimate the free swelling index value. In this investigation, ten input parameters ...
