WebSelective catalytic reduction (SCR) technology is a proven and effective method to reduce nitrogen oxide (NOx) emissions from coal-fired power plants. During the combustion process, the nitrogen that is present naturally in the coal, and the nitrogen and oxygen present in the combustion air combine to form NOx. WebIn certain applications, B&W’s selective non-catalytic reduction (SNCR) technology can be deployed as a relatively low capital cost solution. Our SNCR technology utilizes atomizing nozzles to inject ammonia or urea solutions directly into the hot gas to chemically reduce NOx to nitrogen and water. termites what to look for
