烟气脱硝装置技术介绍

SCR Denitrification Technology and its Application

催化脱硝是目前发达国家普遍采用的减少NOx排放的方法,应用较多的有选择性催化还原法(Selec-tive catalytic reduction,简称SCR)、选择性非催化还原法(Selective non-catalytic reduction,以下简称SCR)。详细介绍了SCR烟气脱硝技术的原理、工艺流程、运行控制和工业应用实例。

The catalytic removal of NOx is widely used in the developed countries,which is an important method in the denitrification of exhaust gas.The catalytic reduction consists of Selective catalytic reduction（SCR） and Selective non-catalytic reduction（SNCR）.This paper describes the principle,technical process,running control and applications of selective catalytic reduction（SCR） for NOx removal from waste gas.
