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 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.
