燃煤电厂烟气脱硫脱硝一体化应用研究

Research on Integrated Application of Flue Gas Desulfurization and Denitrification in Coal-fired Power Plants

燃煤电厂主要是通过燃烧大量的煤炭进行发电的,大部分燃煤电厂为了提高煤炭的燃烧利用率,通常采用煤粉燃烧。但是在实际煤粉燃烧过程中,电厂烟气中含有大量的SO2、氮氧化物等有害物质,严重污染了周边大气环境。近几年,我国生态环境情况日益严峻,国家提出了生态环境建设和发展循环经济的相关政策方针,燃煤电厂也积极响应,越来越注重如何提高燃煤烟气的洁净度。燃煤电厂烟气脱硫脱硝一体化技术应运而生,为提升燃煤烟气的洁净度创造了可能。文章简要介绍了脱硫脱硝技术概念,对燃煤电厂烟气脱硫脱硝一体化技术应用的重要性、具体技术种类以及未来发展趋势进行了论述,以期为相关人士提供参考。

Coal-fired power plants mainly generate electricity by burning large amounts of coal.In order to improve the utilization rate of coal combustion,most coal-fired power plants usually use pulverized coal combustion.However,in the actual process of pulverized coal combustion,the flue gas of the power plant contains a large amount of harmful substances such as sulfur dioxide and nitrogen oxides,which seriously threaten the quality of the surrounding atmospheric environment.In recent years,my country’s ecological environment has become increasingly severe.The state has proposed relevant policies and guidelines for ecological environment construction and the development of circular economy.Coal-fired power plants have also responded actively and have increasingly begun to focus on how to improve the cleanliness of coal-fired flue gas.The integrated technology of flue gas desulfurization and denitrification in coal-fired power plants came into being,creating the possibility to improve the cleanliness of coal-fired flue gas.This article first briefly introduces the concept of desulfurization and denitrification technology,and then discusses the importance of the application of integrated flue gas desulfurization and denitrification technology in coal-fired power plants,specific technology types and future development trends,in the hope that it can provide some ideas for the pioneers reference.
