Web----- Chapter 1 Introduction Selective catalytic reduction (SCR) is a post-combustion nitrogen oxides (NOX) control technology capable of providing NOX reductions in excess of 90 percent.1 With SCR, NOX reductions are achieved by injecting ammonia (NH3) into the flue gas, which then passes through layers of catalyst in a reactor. WebChapter 1 – Selective Noncatalytic Reduction 1-1 1. SELECTIVE NONCATALYTIC REDUCTION 1.1 Introduction Selective noncatalytic reduction (SNCR) is a post combustion emissions control technology for reducing NO x by injecting an ammonia type reactant into the furnace at a properly determined location. This technology is often used …
