基于超低氮排放的精准脱硝控制研究及设计

Research and Design of Precise Denitrification Control Based on Ultra-low Nitrogen Emission

火力发电厂锅炉内燃烧会产生较多的NOx,进而会对环境造成污染,为满足超低排放的要求需要进行精准脱硝研究。基于选择性催化还原技术,对脱硝具体过程编写程序,最终实现喷氨量的控制和脱硝流程的自动化,为现场精准脱硝提供理论依据和技术支持。

The combustion in the boiler of a thermal power plant will produce more NOx,which will cause pollution to the environment. In order to meet the requirements of ultra-low emission,it is necessary to carry out precise denitrification research. Based on the selective catalytic reduction technology,and the specific process of denitration program,the final realization of ammonia injection control and denitration process automation,to provide theoretical basis and technical support for accurate denitration on site.
