摘　　要：以我国2016—2022年部分运营的超300座焚烧厂为研究对象,对单炉处理规模、主蒸汽设计参数、焚烧负荷率等设计和运营参数的变化规律进行统计分析。结果表明:单炉处理规模600 t/d以下的炉排炉数量占比最高,为63.54%,750 t/d及以上处理规模的大型炉排炉数量近些年明显增加;余热锅炉蒸汽参数中温中压(4.0MPa、400℃)占比为59.37%,13.5 MPa、450℃及13.7 MPa、485℃等更高参数焚烧厂数量有增加趋势。2016-2022年,我国垃圾焚烧处理总规模由2.558×10^(5)t/d提高至8.047×10^(5)t/d,同时焚烧负荷率由86.60%下降至72.78%。生活垃圾焚烧发电设施协同处置工业有机固废有助于提升焚烧厂焚烧负荷率,提升技术经济效益。More than 300 incinerators in operation from 2016 to 2022 in China were taken as the research object,statistical analysis was made on the variation rules of design and operation parameters such as single-furnace treatment scale,main steam design parameters and incineration load rate.The results indicated that the number of grate furnaces with a single furnace treatment scale of less than 600 t/d accounted for the highest proportion of 63.54%,and the number of large grate furnaces with a single furnace treatment scale of 750 t/d and above had increased significantly in recent years.The proportion of medium temperature and medium pressure(4.0 MPa,400℃)in the steam parameters of waste heat boiler was 59.37%,and the number of incinerators with higher parameters such as 13.5 MPa,450℃ and 13.7 MPa,485℃ had an increasing trend.From 2016 to 2022,the total scale of waste incineration treatment in China had increased from 2.558×10^(5) t/d to 8.047×10^(5) t/d,while the incineration load rate had decreased from 86.60%to 72.78%.The collaborative disposal of industrial organic solid waste by domestic waste incineration power generation facilities was helpful to improve the incineration load rate of incineration plants and could enhance technical and economic benefits.
