摘要

介绍了河钢邯钢干式高炉煤气TRT机组运行情况。针对出现的静叶调节系统不同步、连接板断裂;机组轴端密封不理想、N_2消耗大;机组实际运行工况点与设计值偏差大,调节精度低等问题分析了原因并提出了改进措施。通过采用双缸控制两侧真实反馈值实时纠偏;在进口煤气管道喷洒专用阻垢剂;轴端改为TRT-FC+ASF组合密封;优化透平动、静叶片叶型;顶压采用PID+前馈数字模型的控制模式等措施,使TRT发电机组发电量显著提高,运行周期明显延长。
        The TRT unit operation of dry blast furnace gas in Hansteel is introduced. Aiming at the problems of unsynchronized adjustable vanes system,broken connecting plate,unsatisfactory shaft end seal,high N_2 consumption,large deviation between actual operating point and design value,and low adjustment accuracy,the reasons are analyzed and improvement measures are put forward. The generation capacity of TRT generating unit is significantly increased and the operation period is obviously prolonged by measures of using double cylinders to control the real feedback value on both sides,spraying special scale inhibitor on the imported gas pipeline,changing the shaft end to TRT-FC + ASF combined seal,optimizing the turbine movement and stationary blade type,and adopting the control mode of PID + feed forward digital model for top pressure.
