A sulfur trioxide conditioning system includes a catalytic converter that converts a portion of the sulfur dioxide in a flow of flue gas to sulfur trioxide. The catalytic converter includes a catalyst support, which is disposed across at least a portion of the cross section of a main duct from a burner to a heat recovery apparatus, and a catalyst on the catalyst support. The amount of the catalyzed surface exposed to the flow of flue gas is selectively varied to control the conversion of sulfur dioxide to sulfur trioxide.
