| 摘 要： | The concentrations of two fresh Chinese coals （lignitie and fatty coal ） from different geological origin and the corresponding fly and bottom ashes were determined using inductively coupled plasma mass spectrometry（ICP-MS）. The ranges and means of concentrations of these elemennts were given. Based on the combustion simulating experiment in the one-dismensional boiler, the contents of REE （rare-earth element） of 18 samples in lignite, fatty coal and their fly and bottom ashes in different combustion condition were determined, and geochemical feature of REE were analyzed.

| Abstract: | The concentrations of two fresh Chinese coals (lignitie and fatty coal ) from dif-ferent geological origin and the corresponding fly and bottom ashes were determined us-ing inductively coupled plasma mass spectrometry(ICP-MS). The ranges and means of concentrations of these elemennts were given. Based on the combustion simulating ex-periment in the one-dismensional boiler, the contents of REE (rare-earth element) of 18 samples in lignite, fatty coal and their fly and bottom ashes in different combustion condi-tion were determined, and geochemical feature of REE were analyzed. |
