Emissions Advantages of Gasification

Gasification based processes for power production characteristically result in much lower emissions of pollutants compared to conventional coal combustion This can be traced to the fundamental difference between gasification and combustion in combustion air and fuel are mixed combusted and then exhausted at near atmospheric pressure while in gasification oxygen is normally supplied to the
