ABSTRACT:
The invention relates to a method and apparatus for desulfurizing flue gas n fuel oil firing systems comprising a residual heat exchanger forming an acid condensate. A neutralizing agent is added to the acid condensate and the neutralized condensate recirculated to the residual heat exchanger for the purpose of dissolving sulfur dioxide. The apparatus for carrying out this method in a fuel oil firing system comprising a residual heat exchanger and a collecting tank for the condensate is provided with a pump and a tank filled with neutralizing agent which are both disposed in a condensate recirculation conduit leading from the collecting tank to the residual heat exchanger.
