摘要
针对目前的引风机裕量过大、运行效率低的问题,提出了3种节能降耗的改造方案:非调速节能方案—切割引风机叶轮外径,非变频调速节能方案—液力耦合器调节,变频调速节能方案—变频调节。以内蒙古通辽霍林河坑口发电有限责任公司的1#机组引风机为例,对3种方案进行详细分析与研究,并对经济效益进行对比计算,从长远的经济效益看,变频调速节能方法是实用、可靠、先进的改造方案,其节能效益可观,是有效减少能量消耗的方法。
In view of the present induced draft fan with too much safety margin and low efficiency,three methods of transformation scheme about energy saving are proposed such as non-speed control energy saving scheme,non-frequency speed control energy saving scheme and frequency speed control energy saving scheme.Taking the induced fan of NO.1 generating unit in the Inner Mongolia Tongliao Huolinhe Power Generation Company as an example,to detailed analysis and research the three methods and economic benefits,from long-term economic benefits,variable frequency regulation is practical,reliable,advanced transform scheme,the energy-saving benefit is considerable,which is effective the method to reduce energy consumption.
