A Research into the Distribution Characteristics & Natural Existing Condition of the Mercury in the Coal of Huainan City

Abstract:

The mercury content in the raw coal is one of the important basic data to estimate the mercury emission of the coal. The outcome of the test and analysis of the mercury content in the raw coal of the 9 mines in Huainan Coalfield has shown that the mercury content in the coal samples of Huainan, although higher than that in the coal of the United States，Russia，Germany，Australia，etc., is within the normal range, with no major differences from that of the coal in North China region. With a research into the content change of the mercury in the coal in the process of washing and in combination with the relevant analysis result of the relation between the mercury in the coal and sulfur, ash content, selenium, we have inferred that the mercury in the coal of Huainan is existing naturally in the minerals, but has come into combination with organic matter in some way or scattered in the organic groups in the form of particles.
