为了研究污泥焚烧炉烟气中重金属和碱金属的分布和分配，在中试燃烧室进行了试验研究。结果表明，采用不同温度下收集飞灰的方法分离烟气中的部分金属是可行的。根据其分离温度，重金属和碱金属可分为三大类：A类包括Zn、K和P，在600℃以上由气相转化为液体或固体。Pb和Cu为B族金属，最适转变温度为400℃。Na和As属于C族，转化温度为300℃。此外，还对温度梯度对重金属和碱金属气固转变的影响进行了实验研究。温度梯度对重金属和碱金属的气固转化有促进作用。然而，过高的温度梯度会抑制细颗粒的形成。K、Pb和Na的转化率峰值出现在434℃s-1， P和Cu的转化率峰值出现在487℃s-1。
In order to study the distribution and partitioning of heavy and alkali metals in the flue gases of a sewage sludge incinerator, an experiment was carried out in a pilot scale combustor. The results indicated that it was feasible to separate part of metals from flue gases by collecting fly ash at different temperatures. On the basis of their separation temperature, heavy and alkali metals could be divided into three groups: group A included Zn, K and P, which converted from gaseous phase to liquid or solid when temperature was above 600°C. Pb and Cu were the metals of group B, with optimum transformation temperature of 400°C. Na and As belonged to group C, with conversion temperatures of 300°C. Moreover, the effect of temperature gradient on heavy and alkali metal gas-solid transformation was also experimentally investigated. It was observed that the temperature gradient could promote the gas-solid conversion of heavy and alkali metals. However, too high a temperature gradient would suppress the formation of fine particles. The peak of conversion rate for K, Pb and Na occurred at 434°C s—1, while that of P and Cu was 487°C s—1.
