| 摘要 |
<p>The invention relates to a method for preventing NOx gas releases contained in flue gases occurring in the calcination from entering into an outlet flow of cooled flue gases. In the method, the flue gases after the calcination are cooled to a temperature of 400-750 °C and they are delayed at this temperature for at least 0.1 seconds, whereby the NOx gases decompose into initial materials.</p> |
