This reaction is sometimes referred to as De-NOx. The reaction between NOx and NH 3 is never perfect, although it can achieve efficiency rates often higher than 95%.
In power stations, the same basic technology is employed for removal of NO x from the flue gas of boilers used in power generation and industry. In general, the SCR unit is located between the furnace economizer and the air heater, and the ammonia is injected into the catalyst chamber through an ammonia injection grid. As in other SCR applications, the temperature of operation is critical. Ammonia slip (unreacted ammonia) is also an issue with SCR technology used in power … Webreduction (SCR) technology. 1 Selective catalytic reduction is a NO x control technology that utilizes a catalyst to reduce NO x to nitrogen and water. Although SCR technology was developed in the United States, other countries such as Japan and Germany have aggressively implemented SCR on coal-fired utility units over the past fifteen
