摘　　要：以南方某城市生活垃圾焚烧发电厂配套的600 t/d炉排炉为研究对象,研究生活垃圾焚烧发电厂协同处置工业有机固废的运行优化调控方法,利用生活垃圾焚烧发电厂的炉排炉开展工业有机固废掺烧试验,通过改变掺烧配比,一、二次风量及各炉排段停留时间,研究掺烧工业有机固废对焚烧炉的影响。结果表明:现有的生活垃圾焚烧发电厂设施可以实现协同处置掺烧量不超过20%的工业有机固废,其中在协同处置量处于低位时,焚烧工况更佳;在实际运行过程中增加一、二次风量都有助于提高炉膛内氧气浓度,从而提高焚烧炉蒸发量,但是二次风更多功能体现在其增加第一烟道烟气扰动、减少炉膛结焦方面;各段炉排停留时间应根据掺烧的垃圾组分进行调节。A 600 t/d grate furnace of a municipal solid waste incineration power plant in southern China was taken as the research object,the operation optimization and control method of cooperative disposal of industrial organic solid waste in the solid waste incineration power plant were studied.By using the grate furnace of the solid waste incineration power plant,the mixing test of industrial organic solid waste was carried out.By changing the mixing ratio,the primary and secondary air volume,and the residence time of each grate section,the effect of mixing industrial organic solid waste on incinerator was studied.The results showed that the existing MSW incineration power plant could realize the collaborative disposal of industrial organic solid waste with less than 20%combustion content,and the incineration condition was better when the collaborative disposal volume was at a low level.In the actual operation process,the increase of primary and secondary air volume was helpful to improve the oxygen concentration in the furnace,so as to increase the evaporation of the incinerator.And the secondary air had more functions in increasing the first flue gas disturbance and reducing the coking of the furnace.The residence time of each grate should be adjusted according to the composition of the mixed waste.
