Abstract：

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.

Key Words： high-sodium coal;sequential extraction;deposition;slagging
