Methods of Determining the Atmosphere Environment Impact Factors of Natural Draft Cooling Towers

Article Preview

Abstract:

The ISC SCREEN3 recommend by the existing guidelines cannot support the atmospheric dispersion modeling of the cooling tower discharge, causing the big difference between the current the atmosphere evaluation class and scope for the project of integrated chimney and cooling tower and the actual environmental impact.In this paper, the model austal2000 which is recommended by VDI3784 standard of the clean air standards established in German is used to calculate the ground concentrations of pollutants discharged by cooling towers, and accounting atmospheric environmental impact assessment class and scope of the unity project of smoke and tower according to the specifications of air guidelines reference. The results show that the most of the smoke and tower integration projects' evaluation level should be 2 and the evaluation radius should be more than 15 km, for the projects with emission of larger pollutants, the evaluation level may reach level 1.
