A method for removing pollutants from flue gas generated by a plant having one or more burners located at an inlet end of a vertically
extending stack (22), the flue gas being discharged through an outlet end of the stack (22). The pollutants are removed by an emission
treatment system (10) which includes a major component module (26) and inlet (40) and outlet (44) ductwork providing fluid
communications between the stack (22) and the major component module (26). The major component module (26) includes an SCR
segment (28), a heat exchanger segment (30), and an ID fan (32), the SCR segment (28) having at least one catalyst unit composed of
materials for selectively catalyzing at least one pollutant. The method comprises the steps of drawing the flue gas from the stack (22) and
through the major component module (26) with the ID fan (32), removing the pollutant from the flue gas with the SCR segment (28) to
produce a clean flue gas, and discharging the clean flue gas to the stack (22) with the ID fan (32).
