Application and Analysis of Direct Air Cooling Technology in Thermal Power Plants

Thermal power direct air cooling unit as a new water-saving way, which has been widely promoted in coal-rich and water-poor regions in China. This article describes the direct air cooling technology devel- opment status, principles and characteristics, the problems of direct air cooling technology highlights and development direction of direct air cooling technology to make predictions. Common problems of direct air cooling technology include dust accumulation on condenser, hot air recirculation, anti-freezing estivate of condenser, fan running and vacuum leak. This paper describes the causes and preventive measures of these problems and generally summaries the research methods.
