Abstract
Waste incineration is one of the most effective means to achieve harmless, reduction and resource recovery. As environmental problems become more and more prominent, increasingly stringent environmental standards will greatly limit the development of conventional waste incineration technology, therefore, the development of a new clean and efficient waste incineration technology will be the inevitable development trend of the waste incineration industry. Based on the computational fluid dynamics (CFD) technology, the structural optimization of the ring oxygen injector used in the oxygen-enriched incineration technology of the waste grate incinerator is investigated. The results show that the oxygen injection ring diameter is 0.7071D, the air duct length is 1.4D, and the oxygen injection ring outer hole is 0.28d and inner hole is 0.4d.
