• 50 The behavior of trace elements from a coal during high temperature process

抄録

The release of trace elements from coal combustion at high temperature was investigated in this study. About 0.1g of Wallarah coal smaller than 150μm was held in a platinum basket, inserted into an electronic furnace predetermined 573〜1573K and burned for 10min to release trace elements. The quantities of trace elements in the coal or ash in the platinum basket after coal combustion were determined by ICP-AES. It was found that initially, trace elements such as Zn and Pb released from a coal above 1173K in the absence of additional steam. Se, Sb and Hg released during 573〜773K and steam influenced the releasing behavior of these elements. Whereas Se and Sb enhanced, that of Hg depressed in the presence of steam.
