In order to avoid or effectively reduce the highly toxic "dioxins" generated during waste incineration, countries have generally adopted oxygen-enriched combustion-assisted technologies to reduce secondary pollution to the environment caused by waste incineration.
The application principle of oxygen-enriched combustion in waste incineration is to enrich the oxygen in the air so that the oxygen content in the enriched gas reaches 25% -30%. Sending this part of oxygen-enriched gas into the incinerator in the form of secondary air can increase the overall or local oxygen content in the furnace and reduce the overall air excess coefficient in the furnace. At the same time, due to the increase of oxygen enrichment, the ignition conditions can be improved, the combustion is complete, the ash and slag are melted, and the volume is reduced to nearly zero, thereby ensuring that toxic organic gases such as dioxins are completely decomposed and combusted at high temperatures. Therefore, the use of Peking Pioneer's oxygen-enriched combustion-supporting technology in waste incineration can not only achieve energy conservation and consumption reduction, but also have environmental benefits.
