介绍了梅钢4号烧结机(400 m2,环冷机460 m2)配套余热锅炉系统的构成和投运情况。针对其运行过程中出现的一些问题,包括工况波动、烟气循环系统设计不合理、环冷系统密封差温降大、设备故障多等,通过一系列工艺调整和设备改造,使之得到了改善,系统产汽量由22~28 t/h提高到35~42t/h,为企业节能减排做出了贡献。
The structure and operation of the waste heat boiler system of No.4 sinter for Meishan Steel (400 m2, 460 m2) were introduced. Aiming at some problems occurred during the operation, including the fluctuation of working conditions, the unreasonable design of flue gas circulation system, the differential temperature drop of the ring cooling system, the failure of equipment and so on, through a series of process adjustment and equipment reformation, Improve, the system of gas production from 22 ~ 28 t / h increased to 35 ~ 42t / h, for the enterprise to make a contribution to energy conservation.
