What Is Selective Catalytic Reduction (scr) Method For No* Control In Gas Turbines ? |
|
Answer» SCR is a POST combustion method in which a catalyst is installed in flue gas where temperature could be of the order of 15-400°C. It enables vaporised NH to react with NO* in exhaust gas to form N2 and H20. Vaporised NH is injected into exhaust gases before it PASSES through the catalyst bed. This process can ACHIEVE in excess of 90% NOX reduction. SCR is a post combustion method in which a catalyst is installed in flue gas where temperature could be of the order of 15-400°C.
