抄録

On-site Bench scale experiments on the removal of mercury from the flue gas of municipal solid waste incinerators using fly ash were performed at site. The fly ash, which was collected from the electrostatic precipitator without using Ca (OH) ₂ spray and which consisted of only dust derived from refuse, had a high mercury removal efficiency. The removal efficiency was most greatly influenced by the temperature parameter. Fly ash gave a high removal efficiency up to 200°C, but the efficiency dropped quickly at 250°C due to the presence of steam. Both HgCl₂ and Hg⁰ could be removed with high efficiency and even steep peaks of highly concentrated mercury were effectively removed. According to the results of continuous experiments, Hg removal efficiency was more than 85% for 2 hours at 180°C using fly ash.The above experimental results proved that the removal of mercury from flue gas using fly ash was very effective.
