直接空冷技术及其应用现状

Direct Air-Cooling Technology and Its Application Status

目前我国大多数火力发电厂都采用湿冷技术,面对日益紧缺的水资源问题,火力发电行业面临前所未有的挑战,而空冷冷却与普通湿冷技术相比可节水2/3。介绍了直接空冷系统的工作原理、特点及直接空冷凝汽器的发展过程,并对直接空冷技术在国内外发展现状及其在建筑节能中的应用做了介绍。考虑到世界各国电力建设和生产现状并结合我国国情,在我国电力建设中直接空冷技术应该被广泛采用。

Water cooling technology is widely used in the domestic thermal power plants. However, water resources are becoming more and more scarce, and the thermal power industry faces unprecedented challenge. To compare with ordinary water-cooling technology, the water can be saved more than 2/3 if the air-cooling system was used. The principle of the direct air-cooling condenser and the characteristics of the development process were introduced and the application status of the direct air-cooling technology at home and abroad and building energysaving was described. Considering the construction of power plants in the world and the situation of our country, direct air-cooling technique should be widely adopted in China.
