    摘要: A combustion apparatus includes a combustion chamber having multiple combustion zones. A first wind box is in communication with the first combustion zone to feed the fuel to be fed into the combustion chamber for initial combustion of the fuel within the first combustion zone. A second wind box has a reburner in communication with the second combustion zone. The reburner is configured to feed fuel, a reagent and a first portion of the flue gas to be recycled to the second combustion zone into the second combustion zone to reduce nitrogen oxide emissions of the apparatus. A third wind box is in communication with the third combustion zone to feed air to the third combustion zone to complete the combustion process.

    摘要: A system includes a selective catalytic reactor and a bypass line. The selective catalytic reactor is located downstream of a furnace that generates flue gases. The selective catalytic reactor reduces nitrogen oxides to nitrogen. The bypass line is in fluid communication with the selective catalytic reactor. The bypass line contacts an input line to the selective catalytic reactor-, where the bypass line is adapted to handle a volume of flue gases diverted from the selective catalytic reactor. A first control damper is disposed at an inlet to the selective catalytic reactor; and a second control damper is disposed at an inlet to the bypass line. The first control damper and the second control damper interact to divide the flue gas stream between the selective catalytic reactor and the bypass line in a ratio to reduce the amount of sulfur trioxide released from the system to a desirable value.
