Abstract: Huaneng Haimen Power Plant 2 × 1036MW unit fan and booster fan are stationary blade adjustable pitch axial fans,as are oversized,the fan is running high power consumption,fan and booster fan is running a bad match. To reduce power consumption rate,the desulfurization fan booster fan to merge with the growth and expansion,to optimize flue gas desulfurization. The implementation of the program, the unit can run at full load power consumption rate declined 0.335 percent, energy-saving effect is remarkable.
1引言
华能海门电厂2×1036MW机组锅炉主设备由东方锅炉(集团)股份有限公司、BHK、BHDB联合制造。锅炉型号为DG3000/26.15-Ⅱ1;锅炉型式为高效超超临界参数变压直流炉、对冲燃烧方式、固态排渣、采用单炉膛、一次中间再热、平衡通风、露天布置、全钢构架、全悬吊结构Π型锅炉。每台机组配备2台AN42e6(V19+4°)型静叶可调轴流式引风机和2台ANT45e6(13)型静叶可调轴流式脱硫增压风机。机组投运后风机耗电率较高,将2号锅炉脱硫增压风机拆除,并对引风机进行增容改造后实现了引风机与脱硫增压风机合并运行。实践证明节能效果显著,平均厂用电率下降了0.25%。此外,对脱硫GGH加热器进行改造,以减少沿程阻力损失,提供风机运行可靠性。本文着重叙述2号炉引增合并后引风机的选型和改造前后经济性分析。
