武钢320t鱼雷罐国产烘烤燃烧器的热态试验研究

HOT TEST OF THE BURNER FOR PREHEATING 320 t TORPEDO LADLE AT WISGCO

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[KG8〗285 m3/h, the adjustment ratio of gas consumption is 55 and CO content in the off gas is less than 1[KG8〗000×10-6 at minimum air coefficient It is also shown that the flame is stable, the flame length is 15 to 45 meters, the noise outside the ladle is lower than 802 dB(A),while the burner works within adjustment ratio range The performance shows that the burner meets the design and technological requirements
