本文介绍了湿式烟气洗涤器（淬冷器）吸收三氧化二硫时硫酸气溶胶形成的实验和模拟结果。只有通过实验和理论相结合的方法，才能对挥发性气溶胶的数量浓度和液滴大小分布进行完整的表征。在中试工厂进行的实验和模拟结果都显示出高浓度。模拟工具预测，在洗涤系统的典型停留时间内，凝结后形成的非常小的液滴甚至保持在亚微米，因此很难沉淀。美国气溶胶研究协会版权所有
Experimental and simulation results of sulfuric acid aerosol formation during absorption of sulfuric trioxide in a wet flue gas scrubber (quench cooler) are presented. The complete characterization of the volatile aerosol with respect to number concentration and droplet size distribution is only possible by combining experimental and theoretical methods. Both experiments performed in a pilot plant and simulation results, reveal high number concentrations. A simulation tool predicts the formation of very small droplets that remain even submicron after coagulation in typical residence times of scrubbing systems and thus are difficult to precipitate.
