Preparation of Domestic Honeycomb Briquette from Corn Stover and Coal

Abstract:

In order to find new ways to utilize agricultural residues corn stover, mixing corn stover, clay and coal to make coal-biomass honeycomb briquette was studied. The effects of shape-forming pressure, biomass proportion, binder’s dosage were investigated by orthogonal experiments. The results show that the factor’s levels have no significant influence on the combustion time of coal-biomass honeycomb briquette. Further experiments indicate that to make coal-biomass briquettes qualified for substituting the marketed coal briquettes the amount of corn stover can reach to 20 percent of the briquettes (dry mass basis) and the shape-forming pressure lowers to 5 MPa. If the content of the corn stover reaches more than 25%, Strength of the honeycomb briquettes will lower than 700 N which is the low limit of the state’s standard though other indexes have on substantial change. Without changing use habit and stove, honeycomb briquettes produced from coal and corn stover can replace the traditional coal briquettes for domestic use, which can be considered as one of the choices to dispose agricultural residues.
