Abstract
Wheat straw, rice hull and candlenut wood were washed by submerging with water of different temperatures. The effect of washing on fuel properties and combustion characteristics of biomass was studied via fuel analysis, thermogravimetric analysis and ash fusibility measurement. The results show that washing can effectively remove K, Na, Cl and S of biomass which may be harmful to boiler operation. After washing, the volatile release and ignition delays and the fusion temperatures of wheat straw ash increase. As the water temperature increases, the removal rate of K, Na, S changes monotonously and the slag of wheat straw turns into short slag gradually.
