摘要

石家庄市燃煤电厂中存在建厂较早、脱硝工艺落后或基本没有的局面。近些年来由于严峻的大气形势,迫使燃煤电厂必须进行工艺升级。石家庄市某电厂循环流化床锅炉脱硝工艺采用SNCR技术。本文针对SNCR技术在实际中的应用要点、暴露的问题及进一步优化做出了初步探索,对其他类似燃煤电厂的脱硝工艺升级具有重要意义。
        In Shijiazhuang coal-fired power plant, there is a situation where the construction of the plant was earlier, the denitrification process was backward, or there was basically no situation. In recent years, due to the severe atmospheric situation, coal-fired power plants have to be upgraded. The denitrification process of a circulating fluidized bed boiler in a power plant in Shijiazhuang adopts SNCR technology. In this paper, the main points of application of SNCR technology in practice, the problems of exposure and further optimization are discussed, which is of great significance for upgrading the denitrification process of other similar coal-fired power plants.
