燃煤电厂烟气脱硝SCR技术还原剂选择的分析

Analysis of SCR Reducing Agent Selection for Flue Gas Denitrification in Coal-Fired Power Plants

随着人们环保意识的不断加强,环保已经成为社会关注的热点问题。燃煤电厂中的烟气脱硝成为一项重要的工艺环节。本文对燃煤电厂的烟气脱硝技术进行简单论述,对选择性催化还原技术(SCR)进行讨论,对SCR技术还原剂的选择进行重点分析。笔者从不同方案的经济性和安全性等方面入手,进行对比分析,以期指导燃煤电厂烟气脱硝工作。

With the continuous enhancement of people＇s awareness of environmental protection, environmental protection has become a hot issue of social concern. The flue gas denitrification in coal-fired power plants has also become an important process link. In this paper, the flue gas denitrification technology in coal-fired power plants is briefly discussed, and the SCR technology is discussed. The selection of SCR reducing agent is mainly analyzed. In order to guide the work of flue gas denitrification in coal-fired power plants, the author makes a comparative analysis on the economy and safety of different schemes.
