Abstract The co-processing of hazardous waste (HW) in cement kilns is a crucial technology for achieving reduction and harmless treatment of HW. The technological process involves high-risk links such as flammable and explosive materials, requiring a complete fire protection system to ensure safe operation. This paper discusses the key points of fire protection design for various process areas in HW disposal, including the liquid waste pretreatment area, industrial hazardous waste storage warehouse, pretreatment workshop, and inorganic solid waste workshop. According to the fire classification and hazard of different areas, applicable schemes for fire protection systems such aswater spray systems, foam fire extinguishing systems, automatic sprinkler systems, and fixed fire monitors are proposed. The design principles of fire pump stations, fire drainage, and accident water tanks are emphasized. The feasibility and compliance of the fire protection system are verified through an engineering case of a cement kiln co-processing project in Xinjiang, providing technical references for similar projects.
