火电厂烟气脱硫脱硝技术应用与节能环保

李哲

摘  要：在当前我国工业化进程不断推进的新形势下，工业化的快速发展对生态环境带来了严重的污染。在当前电能生产过程中，火电还占据较大的比例。火力发展主要以煤炭作为燃料，这就导致火电厂运行过程中会有大量的硫硝物质释放出来，对大气造成严重的污染。因此当前火电厂在生产过程中需要重视烟气脱硫脱硝技术的应用，在减少对生态环境污染的同时，全面提高能源利用效率，这不仅有利于提升火电厂经济效益和社会效益，而且也与节能环保的发展要求相符，对于火电厂的可持续发展具有积极的促进作用。

Abstract： Under the new situation of the continuous progress of industrialization in China， the rapid development of industrialization has brought serious pollution to the ecological environment. In the current process of electric power production， thermal power still occupies a large proportion. The development of firepower mainly uses coal as fuel， which leads to the release of a large number of sulfur and nitrate substances in the operation of thermal power plants， causing serious pollution to the atmosphere. Therefore， at present， thermal power plants need to pay attention to the application of flue gas desulphurization and denitrification technology in the production process， which not only helps to improve the economic and social benefits of thermal power plants， but also plays a positive role in promoting the sustainable development of thermal power plants， which is not only conducive to improving the economic and social benefits of thermal power plants， but also in line with the development requirements of energy conservation and environmental protection.

Keywords： thermal power plant; flue gas desulfurization and denitrification technology; application; energy saving and environmental protection

前言

煤炭作为我国最为主要的能源物质，其多用于火力发电。利用煤炭进行发电过程中会有大量的二氧化硫排入到大气中，从而对生态环境带来较大的污染。火电厂为了能够降低生产过程中对环境的污染，一般都会通过利用脱硫技术来处理二氧化硫物质，但在脱硫过程中存在较大的消耗，因此还要重视烟气脱硫脱硝技术的改进，以此来提高技术的应用效果，降低火电厂生产成本，促进火电厂整体效益水平的提升。

1 火电厂烟气脱硫脱硝现状

火电厂在实际生产运行过程中需要燃烧大量的煤炭，而煤炭燃烧过程中会产生大量的硫酸和硝酸等有害物质，这些物质随烟气排放到空中，必然会对空气质量带来较大的影响，严重危害人体的健康。……
