为分析煤直接液化残渣(液化渣)燃烧处置技术的可行性和环境安全性,采用热重分析仪分析了液化渣、煤和掺烧物料的燃烧特性,并且通过管式炉模拟燃烧试验,研究了不同温度下掺烧过程中苯系物的排放特征.结果表明:煤和液化渣的燃烧特性及二者在燃烧过程中苯系物的排放特征存在较大差异,液化渣主要失重过程的温度区间为560～820℃,明显高于煤的主要失重过程温度区间(230 ～ 625℃).从燃烧过程苯系物的排放规律上看,液化渣在700℃燃烧时苯系物排放量达到最大值,明显高于煤的燃烧温度(500℃).2种物料由于燃烧特性的差异,在掺烧过程中相互影响,使得掺烧过程苯系物的排放规律发生变化.掺烧物料在500℃下燃...

In order to assess the feasibility and environmental risks of coal liquefaction residual (CLR) incineration, thermogravimetric analysis (TG) was performed to study the combustion properties of CLR, coal and their mixture. Co-combustion of CLR and coal was simulated in a high-temperature tubular furnace to study the effect of temperature on benzene compound emissions. The results revealed distinct combustion characteristics and the emission characteristics of benzene compounds of coal and CLR. The maximum weight loss temperature of CLR was 560-820, which was significantly higher than that of co...
