For decades coal has been the fuel of choice for most power stations around the world but also happens to be the most pollutant. The environmental regulation in Europe, China and India has stringent emission limits which coal fired power stations are finding it increasingly difficult and expensive to comply with and are therefore employing such systems as SCR and SNCR.<\/p>

Selective catalytic reduction (SCR) systems are typically found on small and large boilers, gas turbines, diesel engines and even automobiles and have shown to reduce NOx by 70-95%. NOx is one of the primary pollutants generated in a fossil fuel combustion process. Their presence in the atmosphere has a negative impact on the environment (smog, acid, rain, reduced visibility) and human health (respiratory problems) therefore this very same NOx reducing technology is applied to power stations all around the world.<\/p>

C\u00f3mo funciona<\/strong><\/h2>

In the combustion process nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide and nitrogen dioxide NO\u2082. Emission limits for NOx require plants to run DeNOx process in order to reduce the NOx emission below allowable limits.<\/p>

The Nitrogen oxides concentration in the flue gas, can be effectively reduced by reacting them with ammonia water, or urea in high temperature. Ammonia\/urea reacts with both nitrogen monoxide NO and nitrogen dioxide NO\u2082, to produce nitrogen N\u2082 and water vapor H\u2082O and CO\u2082 when Urea is used.<\/p>

SCR DeNOx installations are common for large coal fired power stations, SNCR technology can often be found in small to mid-size incineration plants and power stations utilising CFB boilers.<\/p>

In order to control both SCR and SNCR systems, these processes require monitoring throughout. CODEL offers a range of products that can monitor both input and output gases, flow and dust emissions reliably and accurately using the very latest technology.<\/p>

Key Facts<\/strong><\/h2>

SCR NOx inlet outlet monitoring<\/strong><\/h3>

\u2013 NOx at the inlet is monitored to determine the dose, and control injection of ammonia, fed into the catalyst which in turn reduces the operational costs.<\/p>

\u2013 Outlet NOx is monitored to optimize De-NOx process and assure compliance with environmental regulation.<\/p>

Recommended CODEL products: <\/strong>GCEM 40E<\/strong><\/p>

SCR Flow Control<\/strong><\/h3>

\u2013 Reduced use of reagent by controlling flow and therefore increasing efficiency.<\/p>

\u2013 Monitor catalyst reaction performance.<\/p>

Recommended CODEL products: VCEM 5100<\/strong><\/p>

SNCR NOx<\/strong><\/h3>

\u2013 Control and optimization of denitrification process. Determine and control the dose of ammonia, NH\u2083 fed into the combustion zone.<\/p>
