3 0 3 3 t/h超超临界锅炉无炉水泵启动应用探索

在分析1 036 MW机组超超临界锅炉（3 033 t/h）有无炉水循环泵启动优缺点的基础上,通过在启动过程中协调控制锅炉给水的流量、温度、风量、燃料等参数及启动速度,完成了机组无炉水循环泵的启动,提出了锅炉的运行方式、注意事项和具体操作过程及关键控制要点,对同类机组具有较大的参考性和应用价值。

Research on 3 033-t/h Ultra-Supercritical Boiler Startup with no Circulating Pump

With the analysis of the pros and cons between the boiler startup with and without boiler water circulating pump for the 1 036-MW ultra-supercritical unit, and with the coordinated control of the boiler feed water flow, the temperature, the air flow, fuel and the starting speed during the startup process, the pump free startup is completed. The operating mode, procedures and critical control points for the boilerand the related considerations are proposed, which are practically valuable for the operators in the industry.
