处于水电站上游或枯水期的电厂原水由于有机物的提高,只采用一级除盐的出水水质劣化,采用直接喷淋减温的蒸汽质量劣化,造成汽轮机结垢。1 201×7树脂的出力下降的现象直径为3m的一级除盐阴床周期制水量从投产时15000t下降为8000t甚至6000t,正洗时间延长至1h且出水钠大大超标。开减温器后蒸汽含钠量一般超标,汽轮机叶轮上结有较多钠盐。
The raw water of the power plant located in the upper or lower reaches of the hydropower station is deteriorated due to the increase of organic substances, the quality of the effluent water which is only used by one grade of desalination is deteriorated, and the quality of the steam reduced by the direct spraying reduces the temperature, resulting in fouling of the steam turbine. 1 201 × 7 resin output drop phenomenon The diameter of 3m first-class desalination anion bed cycle water production from 15000t dropped to 8000t or even 6000t, wash time extended to 1h and the sodium exceeded the standard. Open the desuperheater steam sodium content is generally exceeded, the turbine impeller knot more sodium.
