ABSTRACT:
A flue gas conditioning system features a self-contained sulfur burner control loop that operates to maintain a constant desired temperature supply of sulfur dioxide in air by varying the rate of supply of sulfur fuel to the sulfur burner, and the absence of device in the sulfur flow path to measure or monitor sulfur flow rate. In the system, a conditioning agent demand signal operates either a means to supply the sulfur burner with a flow of air, or an air heater in the air flow path upstream of the sulfur burner, or both, to provide conditions that would increase or decrease the temperature of the sulfur burner output absent the self-contained sulfur burner control loop, and as a result of the operation of the self-contained sulfur burner control loop, systems of the invention can provide a demanded flow of sulfur dioxide and air at a substantially constant concentration and a desired temperature to a catalytic converter in response to a conditioning agent demand signal.
