Numerical Simulation of Micronized Re-burning (MCR) Organic Acid Salt Used as an Accelerator

The reaction mechanism of micronized coal re-burning (MCR) organic acid salt used as an accelerator had been described by 81 substances and 564 elementary reactions in this paper. And also the CHEMKIN software had been used to simulate the condition above. In the process of simulation of CHEMKIN, we used acetone as a substitute for Calcium Magnesium Acetate (CMA) to predigest. The results showed as follows: With the rising of the temperature, the falling of re-burning fuel ratio, the increasing of excess air coefficient in re-burning zone and the decreasing of calcium-sulfur ratio, the removal efficiency of NO decreases gradually; While the initiative concentration of SO₂ increases 100ppm at a time, the content of NO decreases 12ppm, which restrains the generation of NO.
