BACKGROUND & AIMS:
:The Kozani-Ptolemais-Amyntaio basin constitutes the principal coal field of Greece. Approximately 50% of the total power production of Greece is generated by five power stations operating in the area. Lignite samples, together with the corresponding fly ash and bottom ash were collected, over a period of 3 months, from the power plant of Amyntaio and analyzed for their content in 16 trace elements. The results indicate that Y, Nb, U, Rb, Zr, Ni, Pb, Ba, Zn, Sr, Cu, and Th demonstrate an organic affinity during the combustion of lignite, while V has an inorganic affinity. Three elements (Co, Cr, and Sc) show an intermediate affinity.
背景与目标:
: Kozani-Ptolemais-Amyntaio盆地构成了希腊的主要煤田。希腊约50% 的总发电量是由该地区运营的五个发电站产生的。在3个月的时间内,从Amyntaio电厂收集了褐煤样品以及相应的粉煤灰和底灰,并分析了其在16种微量元素中的含量。结果表明,Y,Nb,U,Rb,Zr,Ni,Pb,Ba,Zn,Sr,Cu和Th在褐煤燃烧过程中表现出有机亲和力,而V具有无机亲和力。三个元素 (Co,Cr和Sc) 显示出中间亲和力。
