Study on prediction models of biomass ash softening temperature based on ash composition

As a characterization constant of fuel's ash fusibility, ash melting point of fuel plays an important role in the performance of boiler burning. The properties of the ash melting point of fuel have been proved to have close relationships with the contents of oxides in the ash. This paper focuses on finding out general laws to predict the ash melting point of biomass based on the classification of biomass and the analysis of oxides contents. The results of testing and verifying have shown that, the method of biomass ash melting point prediction is effective.
