| With the rapid development of China’s power industry, efficient, lowconsumption and environmental protection has become a factor in the design andconstruction of a modern power plant priority. Air cooling system has been widelyused in the newly-built power unit in arid areas. Its potential and huge economicadvantage and environmental benefits are getting more and more significant. Thepower plant capacity has experienced from small to large, the technology hasexperienced from not hot to mature.The application area has experienced from thetorrid south area to the frigid north area, nebbish to necessary. The developmentprospect become more and more widely. Recently, air cooling power planttechnology has become a hot topic in power plant construction.Direct air cooling system has been widely used in the newly-built powerunit because of the advantage on the flexibility of peak shaving and lowerinfrastructure investment in the air cooling units. As air-cooled exhaust pipe systemsand components important to the island, its pipeline arrangement is reasonable, thepressure drop and flow distribution uniformity steam meets the design and userequirements, affecting the efficiency of air-cooled condenser and winter frostmaintenance is also directly related to the big question generators economicperformance and security.At present, the relevant data on the exhaust pipe system design work is veryadequate, especially for millions of tens of millions in terms of the exhaust pipe. Thesubject application ANSYS, FLUENT, such as computational fluid dynamics (CFD)software to more mainstream1000MW direct air cooling unit arranged high wetsteam flow field and Y-type exhaust pipes arranged in numerical simulation, and thesimulation results are briefly analysis and research. To direct air cooling unit exhaustpipe provides a reference design selection, and direct air cooling unit exhaust pipe tohelp further optimize the design. |
