木屑焚烧过程中氯化氢排放特性研究

Chloride emission character of sawdust incineration was studied using a fixed bed reactor. The effects of combustion temperature, retention time, combustion atmosphere, content of steam on reaction rate were investigated. From experimental results, the kinetic equation was established. The results also demonstrate that Cl-HCl conversion rate increases as combustion temperature rises during combustion. With the increment of retention time, two peaks exist in the emission curve, which suggest that more than two kinds of chlorine exist in the sawdust. There is little effect of oxidative atmosphere on chloride emission. When the reductive atmosphere changes from weak to strong, Cl-HCl conversion rate decreases rapidly. And the existence of steam can accelerate the release of chlorine. The reaction order of sawdust combustion is zero.
