<p><br/>摘 要：简述天津北疆电厂2×1000MW 超超临界机组锅炉引风机选型情况，针对引风机考虑预留脱硝后的压力系数高、流量系数也大的特点，比较了单级和双级动叶可调轴流风机的结构、运行维修、制造、投资特点以及订货情况，最终确定引风机与脱硫增压风机合并设置的形式。文中还分析了合并设置风机后对锅炉及脱硫系统的影响及设计中采取的保护和控制措施，充分保证了锅炉和风机运行的安全性。1000MW 机组取消脱硫增压风机，采用双级动叶可调轴流式引风机在技术、系统的安全运行、设备配套上都是可行的。 <br/>关键词：北疆电厂；引风机；脱硫增压风机；双级动调风机 <br/>Abstract: This paper briefly describe the type selection of boiler ID fan for Tianjin Beijiang Power plant 2×1000MW ultra-supercritical units, introduce the fan type after the merge of ID fan and FGD booster fan, explain the feature of two-stage moving-blade adjusting axial ID fan and it’s order condition, analysis the influence to the boiler and FGD systems after the merge installation of fans. The operation of the boiler and ID fan are safety base on available measures of protection and control. <br/>Key words: Beijiang Power plant, ID fan, FGD booster fan, two-stage moving-blade axial fan <br/> </font></p>
