【摘要】 结合现场实际情况,对济钢400m2烧结机实施了热风点火工程改造。在环冷机2#和3#烟囱之间的烟罩上开口,安装管道,新增高温除尘器、高效耐高温助燃风机、调节阀门、钢结构支架、电气及仪表设备等。热风点火系统投用后,热风温度稳定在240～300℃,点火温度提高到了1100℃以上,混合煤气单耗降低了20.09%,年效益达370.33万元。更多还原

【Abstract】 Combining with actual condition at the field, the reforming of hot air ignition project of Jinan Steel’s 400m2 sintering machine was actualized. The seam was opened in the fume hood between No.2 and No.3 chimneys of annular cooler for installing the pipeline. A series of new equipment were increased, such as high-temperature precipitator, high performance high temperature combustion-supporting fan, regulating valves, steel structure support, electrical installation and instrumentation. After the commissioning of the system, the hot air temperature stabilized in 240-300 ℃, the ignition temperature increased to 1 100 ℃ above, the unit consumption of mixed gas decreased by 20.09% and the annual benefits reached 3.703 3 million Yuan RBM.更多还原
