【摘要】：随着世界人口的增加、工业化的加快,能源消耗量逐年增加,能源的紧缺形式也逐年加剧,节能技术已成为当今科技发展的主流,节能降耗也逐渐成为各工业公司和工厂开展工作的主要目标。本论文将以节能降耗为基本出发点,分析目前各电厂中凝结水泵存在的各类问题,总结凝结水泵进行节能优化改造的各种途径和不同措施。针对内蒙古岱海发电有限责任公司二期#3、#4机组(600MW亚临界空冷机组)凝结水泵的设计压头偏高,节流损失较大,导致系统效率偏低的现象,在性能测试的基础上,从机组安全与节能两方面考虑,分析了凝结水泵存在配套性差、裕量大、泵运行效率较低的问题,进行了凝结水泵通流部分的节能优化改进、变频改造以及运行方式的优化改造。改造后提高了泵与电机的配套性和效率,最高运行效率从改前的74.83%提高到80.12%,扬程下降了87—57m,电机电流下降明显,完全达到了预期的效果,经济效益非常显著。
[Abstract]:With the increase of the world population and the acceleration of industrialization, the energy consumption is increasing year by year, and the energy shortage is becoming more and more serious year by year. Energy saving technology has become the mainstream of the development of science and technology. Energy saving and consumption reduction have gradually become the main targets of industrial companies and factories. This paper will take energy saving and consumption reduction as the basic starting point, analyze all kinds of problems existing in condensate pumps in power plants at present, sum up various ways and different measures for optimizing energy saving of condensate pumps. In view of the phenomenon that the design of condensate water pump of #3Pu #4 unit (600 MW subcritical air cooling unit) of Daihai Power Generation Co., Ltd, Inner Mongolia, is on the high side and the throttling loss is large, which leads to the low efficiency of the system, based on the performance test, Considering the safety and energy saving of the condensate pump, the problems of poor matching capacity, large margin and low efficiency of the condensate pump are analyzed, and the energy saving optimization improvement of the flow passage part of the condensate pump is carried out. Transformation of frequency conversion and optimization of operation mode. After revamping, the matching performance and efficiency of pump and motor are improved, the maximum operating efficiency is increased from 74.83% to 80.12%, the head is reduced by 87-57 m, the motor current is obviously decreased, the expected effect is completely achieved, and the economic benefit is very remarkable.
