Abstract:
In order to research the influence of the form of hole and holes' relative position on stability and pressure distribution of natural draft cooling tower(NDCT)with flue gas injection, taking China's highest and biggest super large-scale cooling tower with flue gas injection which used this technology as study object, the wind pressure distribution and whole drag coefficient were compared around open hole flue about cooling tower with flue gas and without flue gas in wind-tunnel test, then the characteristics of local wind pressure distribution around the flue gas of cooling tower weregained. Finally, the whole strength's influence caused by changing angle of two holes' relative position was considered, and the strength performance of a lone cooling tower without the hole was compared with. The results show that the changing of two holes' relative position has great influence on whole drag coefficient; the whole drag coefficient of cooling tower with open hole is bigger than that of cooling tower without open hole.
