What type boiler and fuel are you planning on firing? Flue gas recirculation (FGR) is typically used to lower NOx emissions and is ducted into the burner windbox or into an air zone of the burner it self. I'm not sure what it has to do with cleaning burners on line. My gut feel is that FGR would prevent or make for some expensive ductwork configurations to permit cleaning burners on line. I would think that the manufacturers may need FGR to make emissions guarantees and that the cleaning on line option would drive up the installation costs.
: Can anyone tell me anything abou flue gas recirculation pros and cons. We are replacing a boiler and we would like for it to have burners that can be cleaned on line, but the boiler manufactures say that to have this option we must have flue gas recirculation. I don't know anything about it good or bad. Can any tell me anything or tell me wher to go .
: Thanks
