The geochemistry of tungsten in Bulgarian coals ...

01/11/1982  This paper discusses the tungsten geochemistry in coal, based on the behavior of this element in 14 Bulgarian deposits. The W contents range from 0.5–4335 ppm in the ash and from 0.01–784 ppm in the coals. In four of the deposits the tungsten content proved to be 16 to 100 times higher than the Clarke value for sedimentary rocks. No correlation has been found between the W concentration and either the age of the coal-bearing strata or the coal rank. The deposits

01/01/2013  Yenikoy power plant is a coal-fired electric power station with a 2 × 210 MW production capacity located in Mugla, Turkey. The plant burns a low quality, high calcium lignite, which causes significant operational problems due to slag formation in combustion units over time. This study aimed to characterize the ash deposits taken from one of the boilers of this particular power plant. The

26/10/2017  In the thirsty Thar desert, Pakistan has begun to dig up one of the world’s largest deposits of low-grade, brown, dirty coal to fuel new power stations, with Chinese investments. Description: While the rest of the world is hopefully clamping down on coal, Pakistan is planning to increase lignite mining with five new power plants scheduled to start producing electricity by 2018 and many more in the

With many different methods used to express efficiency performance, it is often difficult to compare plants, even before accounting for any fixed constraints such as coal quality and cooling-water temperature. Practical guidelines are presented that allow the efficiency and emissions of any plant to be reported on a common basis and compared against best practice. A ...

21/06/2021  The Rukwa coalfields comprise the Mkomolo, Namwele, and Muze deposits, hosting 173 million tonnes of measured and indicated coal, sufficient to support a 120 MW coal-fired power plant for 30 years. In FY 2019, total production amounted to 37,239 tonnes, compared to 75,442 tonnes in FY 2018 (-51%). The decrease was partly due to lack of working capital to complete a planned mine

Deposit Formation of the Low-Pressure Economizer in a

A field study was conducted to investigate the deposit formation of the low-pressure economizer (LPE) in a 330 MW thermal power plant. The deposits on the LPE were inspected visually, and eight deposit samples were collected at the inlet and outlet of the LPE according to the site conditions. The samples were characterized by X-ray fluorescence, X-ray diffraction, scanning electron microscopy ...

Coal and lignite based power plants have approximately 54.42% of the total electric power generation capacity in India. However, relatively lower calorific value, coupled with high ash content and inefficient combustion technologies aggravates emission of greenhouse gases and other pollutants from India’s coal and lignite based thermal power plants. Main emissions from coal fired and lignite ...

Coal in the Balkans - Bankwatch

Ageing coal power plants and open-cast lignite mines play an important role in aggravating the situation. The Chronic Coal Pollution report, published by the Health and Environment Alliance, Bankwatch and others, showed that in 2016, 16 coal power plants in the Western Balkans emitted as much dust and sulphur dioxide as all the 250 plants in the EU. As a result, it is estimated that they are ...
