The Experimental Study of the Influence of Mg-Based Additives on Wheat Ash Melting Point

摘要

In this paper, the influence of additives on the wheat straw ash melting point was studied. Four kinds of Mg-based additives are added to wheat ashes, including MgCl_2?6H_2O, MgO, MgSO_4 and C_4H_6O_4Mg?4H_2O. The results show that MgO is the most effective additives, MgCl_2?6H_2O and MgSO_4 in the next place, while C4H6Subscript textO4Mg?4H_2O makes ash melting point decreased. The effective additive amount of the MgO, MgCl_2?6H_2O and MgSO_4 are: 0.35 g/g ash, 0.5 g/g ash, 0.75 g/g ash especially.
