STUDY ON THE PARAMETERS THAT INFLUENCE THE EFFICIENCY OF DE-NO IN ADVANCED NATURAL GAS REBURNINGAREA BY EXPERIMENTALAND KINETIC MODEL

The parameters that influence the efficiency of de-NO in advanced natural gas reburning area have been studied by the experimental and kinetic model. It shows that the efficiency of de-NO is low when the temperature less than 1050℃, while it is high when the temperature reaches 1100℃ -1200℃. With the increasing of initial NH3/NO, the efficiency increases with quick at first and slower after then. There exists an optimum value for excess oxygen ratio. The value of initial natural gas/NO exists optimum at about 3 for the system. With the revised kinetic model, the calculation becomes more accuracy.
