【摘要】 发电厂生产过程中常采用循环水泵不同组合方式来维持凝汽器最佳真空。以某公司3号、4号300MW机组为例,介绍了确定循环水泵最佳组合运用方式的3种方法(计算法、试验法和统计法)。对这3种方法的优缺点进行比较后,指出统计法最为实用。更多还原

【Abstract】 In Power-generating production, the optimal vacuum in condenser is commonly maintained by using different combination mode of the circulating water pump. Taking two 300 MW units no.3 and no.4 in one company as example, three methods for determining the optimal operation mode of circulating water pumps, i.e. calculation method, test method, and statistic method, have been presented. After comparison of advantages and disadvantages of three said methods, the statistic method to be the most suitable one for practical use has been pointed out.更多还原
