Effect of Chlorine on Combustion Process of Pulverized Coal in Tuyere Zone

Abstract:

The relation between chlorine and combustion process of pulverized coal in tuyere zone is affected by the existence form of chorine in coal. The combustion process of pulverized coal in tuyere zone is restrained by chorine of coal when the existence form of chorine is chloride created by Cl^- and metal cation. The combustion process of pulverized coal in tuyere zone is improved by chorine of coal if chorine existents with the form of combination of HCl and nitrogen functional groups of coal macromolecules. Under the combustion conditions of tuyere zone in blast furnace, the distribution ratio of chlorine in unburned pulverized coal and blast furnace gas is approximately 60% and 40%, respectively.
