The invention belongs to the technical field of
oxygen-enriched
combustion of rotary kilns, and relates to an
oxygen-enriched distribution adjustable
rotary kiln burner for
hazardous waste treatment, which comprises an inner sleeve component and an outer sleeve component which are coaxially sleeved, and a gas channel is formed between the inner sleeve component and the outer sleeve component. The outer sleeve
assembly comprises a first outer cylinder and a second outer cylinder which are coaxially arranged in a sleeved mode, and an outer
air channel is formed between the first outer cylinder and the second outer cylinder. The inner sleeve
assembly comprises a first inner cylinder and a second inner cylinder which are coaxially arranged in a sleeved mode, the first inner cylinder is located in the second inner cylinder, and an inner
air channel is formed between the first inner cylinder and the second inner cylinder. Flexible adjustment of the concentration and the position of
oxygen-enriched gas in the whole circumferential direction is achieved, then flames are controlled to form a proper flow field, an
atmosphere field and a temperature field in the circumferential direction, control over the temperature in the
rotary kiln is facilitated,
combustion reaction is conducted in the high-temperature and high-oxygen environment, harmful substances are converted into harmless gas or
solid products, and the
combustion efficiency is improved. Meanwhile, combustion-supporting gas is saved.
