ABSTRACT

ISWAN. A Study on the Pollution Model of Emission Distribution Caused by Coal-fueled Steam Electrical Power Plant (supervised by Nadjamuddin Harun and Salama Manjang). 

This is a research to study the air pollution caused by a coal-fueled steam electrical power plant to be located in the village of Nii Tanasa, Suropia in the district of Konawe, South-East Sulawesi, Indonesia. The emission distribution model has been used for analysis. Several data such as the wind velocity, air pressure and other climatologically atmospheric observation data as well as the plant’s technical specification should be provided to develop a fairly accurate model. Gaussian distribution is assumed to be the statistical model to approximate the pattern of gas emission from the chimney.

The computation using the model has shown that SO2 gas concentration will reach the values between 0.37 to 0.50 mgram/m3 at the distance of 2000 meter from the chimney. The dust concentration will be located at the distance of 800 to 900 meter from the chimney, reaching the amount of 6.1 to 7.8 mgram/m3.  It is also concluded from the analysis that the increasing wind velocity will reduce the SO2 gas and the dust concentration emitted from a certain diameter and height of the chimney.
