doi:10.11930/j.issn.10.11930.2015.4.27

Abstract

Abstract: Aiming at the existing problems in SCR system due to the lack of SCR engineering design experience in the country, such as short lifecycle of SCR catalyst, high equipment erosion, high ammonia slip and SO2/SO3 transforming ratios, the principles and key techniques for SCR engineering design are introduced based on the foreign and domestic experiences as well as the summaries of continuous research and development practices. In particular, the effects and applications of the techniques are presented in details. Meanwhile, the analysis on the problems arising from the current SCR design and operation is conducted, and the technical precautions for the design are proposed to improve the application level of the SCR technology so that SCR can reach higher efficiency, better economic performance and higher reliability.

Key words: thermal power plant, NOx emission, SCR denitrification, design principle, improvement
