Abstract
西北区域近年来间接空冷投运较多，间接空冷机组因防冻措施及现场测点问题造成现场发生空冷散热器损坏事故时有发生，给电厂带来严重的经济损失，本文从防冻逻辑和防冻增设温度测点两个方面入手对间接空冷防冻进行了研究，优化了现场实际的防冻措施，提高了机组安全稳定运行的可靠性。 More indirect air cooling systems put into operation in northwest China in recent year. The accident of air cooling radiator in the field often happens, which brings serious economic loss to the power plant. The mean reasons of this are anti freezing measures and site measurement. This article starts from the aspects of antifreeze logic and anti-freeze temperature measurement. It studies the indirect air-cooling and antifreeze, optimizes the actual antifreeze measures on site, and improves the reliability of the unit's safe and stable operation.
