Paper Title:
Ash Characteristics Analysis during Co-Combustion of Biomass and Coal
  Abstract

The ash characteristics is closely related to the fuel compositions, and chemical reactions happened between the compounds of ash during co-combustion of biomass and coal. Through the phase compositions analysis of ash from co-combustion of biomass and coal, the results show that KCl(g) mainly reacts with aluminosilicates to form potassium-aluminosilicates and part of KCl(g) also can be sulfated by SO2 during co-combustion. In the fuel, CaO and MgO may react with aluminosilicates to form CaAl2Si2O8 and Mg3Al2Si3O12 with low melting temperature, which can reduce the content of potassium-aluminosilicates and drop the ash melting point temperature.
