As the amount of domestic waste is increasing,land resources are becoming more and more scarce,and management and maintenance are difficult in the follow-up stage,landfill technology has gradually showed its drawbacks.Domestic waste incineration technology has gradually become the mainstream garbage disposal method in our country because of its small footprint and high reduction degree.Due to the promotion of waste incineration technology,some domestic waste incineration enterprises have a situation of"insufficient garbage volume",and the technology of mixed burning of stale waste has been put on the research agenda.The proportion of combustible materials in the stale waste buried within 7 years is 77.88％～80.69％,and the calorific value is 4 114.7～5 332.7 kJ/kg.The sorted stale waste is suitable for incineration disposal.The proportion of stale waste blending shall not be higher than 20％.The evaporation of waste heat boiler is slightly lower than normal,and the production of slag is slightly increased after mixed burning with stale waste.Through the scientific summary of the utilization of stale waste,the complete technical route of recycling of stale waste is obtained,which aims to provide reference for the utilization of stale waste.
