Application Of No_x Reduction Technology In The600MW Coal-fired Units

This paper has introduced the various technology of NOx emissions reduction, aswell as relevant laws and regulations and related standard, by comparing theadvantages and disadvantages of all kinds of NOx emission reduction technology, andexplains the current stage denitration technology is the best option of coal firedpower plants for NOx emission reduction, and focus on the discussion of theselective catalytic reduction denitration technology. The selective catalytic reductiontechnology principle, system composition, main equipment, etc were described indetail in this paper; And through comparing and analyzing the eight well-knownenterprise’s technical characteristics worldwide that can provide selective catalyticreduction denitration system. This paper also do a simple introduction of theapplication of SCR at home and abroad, and to discuss analysis Fujian ZhangzhouHouShi power plant’s selective catalytic reduction denitration system as anexample,the same type of domestic power plant of Zhanjiang Zhongyue Energy co.,LTD. This paper mainly introduces a certain power plant unit2x600MW that havethe same type of Zhanjiang Zhongyue Energy co., LTD. Who is provided the selectivecatalytic reduction denitration technology characteristics by the Eastern BoilerTechnology co., LTD, The data that were collected through the performanceoptimization test were analyzed,and evaluat the application effect of that powerplant’s selective catalytic reduction denitration system in600MW coal-fired powerplant that was provided by The Eastern Boiler co., LTD. dispose what should focus onin the optimization of reducing NOx emission later and reconstruction scheme thatcan be referenced to the reducing NOx emission.
