中文摘要：

严肃的犯规和起炉渣的问题由于它钠(Na ) 的高内容与中国 Zhun 盾煤的燃烧被联系。在燃烧期间理解 Na 的版本特征对这煤的可行利用必要。在这个工作，煤样品与溶剂的一个序列被对待：水(H ₂ O ) ，铵醋酸盐(NH ₄ 交流) ，盐酸酸(HCl ) ，和 Na 的各种各样的班的版本特征用导致激光的故障光谱学的技术在煤燃烧期间被调查。到 Na 的班在每个燃烧阶段期间释放的各种各样的 Na 的相对贡献被发现类似，在 H ₂O 可溶的 Na > NH ₄ 交流可溶的 Na >HCl 可溶的 Na > 不可溶解的 Na。在液化作用阶段期间释放的钠能被归因于每钠班。在液化作用阶段以后， H ₂O 可溶的 Na 和 NH ₄ 交流可溶的 Na 在字符和灰阶段期间统治了 Na 版本。在燃烧期间释放的超过 64% 全部的 Na 来自 H ₂O 可溶的 Na，它建议 Na 版本能被 H ₂ O 洗。

英文摘要：

Serious fouling and slagging problems are associated with the combustion of Chinese Zhun-Dong coal due to its high content of sodium （Na）. Understanding the release characteristic of Na during the combustion is essential to viable utilization of this coal. In this work, coal samples were treated with a sequence of solvents： water （H2O）, ammonium acetate （NH4Ac）, hydrochloric acid （HC1）, and the release characteristics of various classes of Na during coal combustion were investigated using the technique of laser-induced breakdown spectroscopy. The relative contribution of various Na classes to the Na release during each combustion stage was found to be similar, in the order of H2O-soluble Na 〉 NHaAcsoluble Na 〉 HCl-soluble Na 〉 insoluble Na. Sodium released during the devolatilization stage can be attributed to each of the sodium classes. After the devolatilization stage, H2O-soluble Na and NHaAc-soluble Na dominated the Na release during both char and ash stages. Over 64 % of the total Na released during combustion comes from the H2O-soluble Na, which suggests that the Na release during the combustion of Zhun-Dong coal can be reduced effectively after treatment by H2O washing.
