为了降低高钠煤在燃烧和气化过程中对电厂锅炉、加压循环流化床等的影响，根据钠在煤中的赋存形态，介绍了主要的钠研究方法，包括逐级提取、组分分离和低温灰化。在高钠煤的加工处理中可以采用以下方法降低其负面效应：改进锅炉局部区域的设计温度，尽可能使钠化合物停留在灰分中；通过动力煤分选；煤炭加工利用前，通过特殊试剂交换煤中的可溶性钠；添加可以与钠作用的物质。对新疆等地区高钠煤的利用提出了研究建议。

To reduce the influence of high-sodium coal combustion and gasification on power plant boiler and pressurized CFB. Based on the speciation sodium in coal,introduced the main research methods including sequential chemical extraction technology,component sepa-ration and low temperature ashing.To reduce the impact of sodium,transformed the design temperature of boiler,so most of sodium com-pounds can stay in ash.Separated the raw steam coal.Before processing,replaced the sodium in coal with special agents.Added special a-gents which can react with sodium.Provided suggestions for Xinjiang high-sodium coal utilization.
