Research Of Physical Chemistry Character Of Organic Acid Salt Accelerator By Reburning

Physical chemistry character of organic acid salt as accelerator in the situation of pulverized coal reburning have been analyzed, and found that CMA was a suitable accelerator. And established the model of de-NOx, finally we can use 81 matters and 564 reactions to describe mechanism. Through chemkin software, simulation of NO_x reduction reactions was carried out. During the simulation, acetone was substitute for CMA for simplification, results showed that the efficiency of reduction NO reduction can decrease along with temperature and SR2 increased, secondary fuel and Ca/S decreased,but H₂S is contrary; if initial concentration of SO₂ increased 100ppm, NO would decreased 12ppm, so SO₂ can suppress NO production; SO₂ would transformed into SO and S in reburning zone.
