Rotary kiln incineration systems are widely adopted in the international industrial waste treatment sector, holding an approximate market share of 85% in this field. They are also recommended by China’s Ministry of Science and Technology and the National Environmental Protection Agency as the preferred furnace type in the National Industrial Waste Treatment Technology Policy. These systems can simultaneously handle sludge, industrial waste and waste with high moisture content. Solid waste is conveyed into the rotary kiln where it undergoes moisture evaporation, volatilization, ignition, and complete combustion. Ash residue is discharged through an outlet at the kiln’s tail end, while the generated flue gas proceeds to a secondary combustion chamber. Here, it mixes with secondary combustion air to ensure thorough burning, leading to the safe and compliant discharge of exhaust gases. Key features of rotary kiln incinerators include their broad adaptability to various wastes, ease of operation and maintenance, and extended service life.
