- Sainmhíniú "technique to reduce PCDD/F and mercury emissions in the air by passing flue gas through a moving-bed filter using an adsorbent (e.g. activated coke, activated lignite or a carbon-impregnated polymer) to remove pollutants" Tagairt "COM-EN, based on: European Commission. Joint Research Centre. Best Available Techniques (BAT) Reference Document for Waste Incineration (16.4.2019)"
- Nóta An essential feature of the moving bed system is its high efficiency with all emissions due to the large bulk of activated coke, so that variations from incineration and upstream flue-gas cleaning caused by operation will not cause adverse effects. The flue-gas is guided to the activated coke filling over a distributor bed equipped with a multitude of double funnels. The gas flows through them from the bottom to the top or horizontally, while the HFC passes through the absorber from the top to the bottom. In this way, an ideal distribution of the flue-gas over the whole cross-section of the absorber and an optimal utilisation of the absorber capacity are achieved with a minimum consumption of activated coke.
