Abstract:Xinjiang high alkali coal contains a large amount of alkali metals,which cause serious slagging and fouling during the combustion process.This paper summarizes the principles of slagging and fouling during the combustion process of Xinjiang high alkali coal,and proposes corresponding solutions i.e:advantages and disadvantages of pre combustion water washing leaching technology;the influence and optimization of combustion parameters during the combustion process;inorganic additives,other coal and Xinjiang high alkali coal mixed combustion technology.Further feasible research directions are proposed for the efficient utilization of Xinjiang High Alkali Coal in power plant boilers.
