WebSCR system design basics. The SCR process involves the reduction of NOx to nitrogen and water by the reaction of NOx with ammonia with the aid of a catalyst: 4 NO + 4 NH3 + O2 - 4 N2 + 6 H2O. 2 NO2 + 4 NH3 + O2 - 3 N2 + 6 H2O. An ammonia-air or ammonia-steam mixture is injected through an injection grid into exhaust gases containing NOx. WebEl SCR. El rectificador controlado de silicio es un tipo de tiristor formado por cuatro capas de material semiconductor con estructura PNPN o bien NPNP. El nombre proviene de la unión de Tiratrón (tyratron) y Transistor. Un SCR posee tres conexiones: ánodo, cátodo y gate (puerta). La puerta es la encargada de controlar el paso de corriente ...
