About author:Wang Fengyu, a senior engineer, obtained his bachelor’s degree in inorganic non-metallic materials engineering from Wuhan University of Science and Technology in 2011 and is currently pursuing a master’s degree at the same university. He works for Beijing Jinyu Tongda Refractory Technology Co., Ltd., specializing in the design and R&D of refractory materials for solid waste and hazardous waste incinerators in environmental protection industries. He has won one Second Prize of Beijing Science and Technology Progress Award and three Second Prizes of Building Materials Industry Science and Technology Progress Award issued by China Building Materials Federation.

Abstract

Abstract: The material selection, refractory products design, and engineering application for rotary kilns in hazardous waste disposal in China were summarized in this paper. Unified specifications for rotary kilns regarding brick shapes, masonry proportioning, refractory material selection, and the core equipment of incinerators were established. The group standard T/CMCA 40022-2021 was compiled to provide standardized, replicable technical solutions for hazardous waste disposal enterprises of different regions and scales. Extensive field verification shows that standardized design and material selection effectively lower the manufacturing, replacement, and maintenance costs of rotary kiln refractory bricks, greatly improving the operation stability of hazardous waste incineration rotary kilns and prolonging the service life of refractory bricks.

Key words: hazardous waste incinerator, standardized design, material selection, chrome-zirconia-corundum brick
