%X 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 separation and low temperature ashing. To reduce the impact of sodium,transformed the design temperature of boiler,so most of sodium compounds can stay in ash. Separated the raw steam coal. Before processing,replaced the sodium in coal with special agents. Added special agents which can react with sodium. Provided suggestions for Xinjiang high-sodium coal utilization
