Particle size and particle size distribution. Fraction PM10 and PM2,5. Particulate matter removal. General equation of particle motion. Gravitational, inertial, centrifugal and electrical principle of separation. Diffusion of particles. Total and grade efficiency of separation. Pressure drop. Classification of particle separators, basic characteristics.
Principles of gaseous pollutants removal. Desulphurization - classification of methods. Dry additive method, intensification, wet-dry calcium oxide method, wet limestone method - principles and basic characteristics. Fuel combustion and nitrogen oxide formation. Primary denitrification methods. Secondary denitrification methods - principles and basic characteristics.
Propagation of pollutants in the atmosphere. Vertical temperature gradient. Stability class of the atmosphere. Wind speed distribution, wind classes, vertical wind profile, wind rose. Gaussian plume model of the pollutant dispersion from point source. Pollution calculation.
- Syllabus of tutorials:
