Abstract
A system for enhancing the efficiency of an electrostatic precipitator in a flue gas stream that withdraws a selected amount of combustion gas from a main flue gas stream at a location downstream of the electrostatic precipitator; typically heats the selected amount of combustion gas to a predetermined temperature; passes the selected amount of combustion gas through a catalyst to convert sulfur dioxide to sulfur trioxide producing a mixture of flue gas enriched with sulfur trioxide; and returns the mixture of the flue gas enriched with the sulfur trioxide back into the main flue gas stream at a point upstream of the electrostatic precipitator. A controller can control fans, heaters and dampers as well as make computations as the required amount of sulfur trioxide needed.
