一、前言 宝钢自备电厂的两套35万瓩机组为国内容量最大的机组,其冷凝器采用国际上最先进的钛管冷却方式,由日本三菱重工长崎造船所制造。原设计寿命为30年(26万小时),但实际上1号机组运行15000小时后,2号机组运行8600小时后,均有一根钛冷却管泄漏,很多钛管已有不同程度的损伤。钛管泄漏后,将使水质交坏,为避免水质恶化,需不时放水放气,既浪费了能源也消耗了许多优质水,
I. Foreword Two sets of 350,000 units of Baosteel-owned power plants are the largest units in China. The condenser adopts the most advanced titanium tube cooling method in the world and is manufactured by Japan’s Mitsubishi Heavy Industries Nagasaki Shipyard. The original design life of 30 years (260,000 hours), but in fact Unit 1 operation 15,000 hours after the Unit 2 operation 8600 hours, there is a titanium cooling pipe leakage, many titanium tubes have different degrees of damage. Titanium tube leakage, will make the water worse, in order to avoid deterioration of water quality, from time to time to drain the gas, both waste of energy and consume a lot of high-quality water,
