宁东基地燃煤电厂原料煤及副产品中稀土元素富集规律研究OA
Study on Enrichment Law of Rare Earth Elements in Raw Coal and Its By-Products in Coal-Fired Power Plants in Ningdong Base
采用电感耦合等离子体质谱法(ICP-MS)测定了宁东基地鸳鸯湖电厂、马莲台发电厂原料煤及副产品中稀土元素的质量比并探究了稀土元素的富集规律.结果表明:鸳鸯湖电厂原料煤中稀土元素的富集系数表现为正常;马莲台发电厂原料煤中La,Ce,Y的富集系数表现为轻度富集,其余稀土元素的富集系数表现为正常;两个电厂原料煤中的轻稀土相对于中稀土及重稀土明显富集;煤燃烧后稀土元素主要富集在炉渣、粗灰、细灰中,并且更容易富集到细灰和粗灰中,炉渣次之;副产品中的稀土元素…查看全部>>
Inductively coupled plasma mass spectrometry(ICP-MS)was used to determine the mass ratios of rare earth elements in the raw coal and by-products of Yuanyang Lake Power Plant and Maliantai Power Plant in NINGDONG Base,and to investigate the enrichment pattern of rare earth elements.The results showed that the enrichment coefficients of rare earth elements in the raw coal of Yuanyang Lake Power Plant were normal;the enrichment coefficients of La,Ce,and Y in th…查看全部>>
