dioxin >99% removal 有左幾十年啦...
而家係講緊NOx、Chloride等等都>99% removal
organic chem離渣喎師兄,
係syllabus三十年都有
你唔讀理科都好,
焚化爐接近零毒氣係通識d公廁範文離
你究竟係無撚上堂定未到高中
Modern incinerators currently operating in Europe and Asia employ technologies to sharply reduce dioxins. Furnace temperatures have been raised to levels above 850°C, and methods have been developed to better trap fly ash, better clean the boilers and remove dust. Abatement technology has also been added to reduce nitric oxides and other airborne pollutants. Periods of incinerator startup and shutdown, when furnace temperatures pass the dangerous 200°C to 600°C threshold, are minimized with steady supplies of waste.
As a result, dioxin emissions from incinerators with modern abatement technologies are currently near zero. Modern incinerators also include processes to generate electricity, heat water for district heating services, recycle the metals found in the ashes and build tiles from the remaining slag. Studies have found these incinerators can serve as carbon sinks if the energy they produce displaces coal.
