氨冷凝器漏氨对水冷器设备影响状况及分析

EFFECT ON WATER COOLER BY AMMONIA-LEAK FROM AMMONIA CONDENSER AND ANALYSIS

介绍氨冷凝器氨泄漏后循环水中氨的状况,根据水冷器设备及地下管网腐蚀和结垢的检查情况,以及对监测试片、监测换热器试管的腐蚀情况和水冷器垢样数据的分析情况,表明氨冷凝器长期漏氨对水冷器设备有结垢沉积,并直接和间接引起水冷器设备腐蚀增加。

The ammonia level in circulation water once ammonia is leaked irom the condenser, me cor- rosion and fouling inside the water-cooler and under-ground piping network are introduced as well as the corrosion on monitoring test-blocks, test-tube of monitoring heat-exchanger and data of fouling sample in wa- ter-cooler are analyzed;all those show that a long-term ammonia-leak from the condenser may cause the wa- ter-cooler to have a fouling deposits and this may directly or in-directly lead to a corrosion increase in the water-cooler.
