直接空冷系统研究现状与发展前景
|
摘要
我国北方地区富煤缺水,因此,大型火力发电厂多采用直接空冷技术。从直接空冷系统的研究现状、直接空冷技术研究方法以及该技术有待解决的关键问题等方面进行论述,并对发展前景进行预测。
In north China, coal is abundant and water is scarce, so direct air cooling technology is often used in large thermal power plants. In this paper, the research status of direct air cooling system, the research methods and the key problems to be solved of direct air cooling technology are discussed, and the development prospect is forecasted.
