摘要
通过对研制的武钢320t鱼雷罐烘烤燃烧器进行1∶1的热态试验研究,得到了该燃烧器的各项技术性能:燃烧器点火时间<4s,无明显着火延迟;燃烧能力(煤气流量)为1285m3/h;燃烧能力调节比为5.5;在最小空气消耗因数n=1.035下工作时,燃烧废气中CO<1000×10-6;在调节比正常范围内工作时,燃烧火焰稳定,火焰长度为1.5~4.5m,罐外噪音最大为80.2dB(A)。该燃烧器的各项技术性能达到了设计目标并满足了武钢生产工艺要求。
The performance indexes of the burner for preheating 320 t torpedo ladle have been obtained by a full scale hot test It is shown that the ignition time of the burner is less than 4 seconds, the maximum gas consumption is 1[KG8〗285 m3/h, the adjustment ratio of gas consumption is 55 and CO content in the off gas is less than 1[KG8〗000×10-6 at minimum air coefficient It is also shown that the flame is stable, the flame length is 15 to 45 meters, the noise outside the ladle is lower than 802 dB(A),while the burner works within adjustment ratio range The performance shows that the burner meets the design and technological requirements
