Abstract

UN METODO PARA VAPORIZAR UN AGENTE DE REDUCCION ACUOSA PARA REDUCIR NOX EN GAS DE COMBUSTION EN UN SISTEMA DE COMBUSTION. UN INTERCAMBIADOR DE CALOR ESTA DISPUESTO EN LA TRAYECTORIA DE GAS DE COMBUSTION DE MANERA QUE EL CALOR DEL GAS DE COMBUSTION CALIENTE UN MEDIO DE TRANSFERENCIA DE CALOR, PREFERENTEMENTE AIRE AMBIENTE. EL AIRE CALENTADO PASA A UN RECIPIENTE VAPORIZADOR DONDE SE VAPORIZA UN AGENTE DE REDUCCION ACUOSA, PREFERENTEMENTE AMONIACO ACUOSO. EL AMONIACO VAPORIZADO ES INYECTADO DENTRO DE LA TRAYECTORIA DE GAS DE COMBUSTION DONDE ES EFECTIVO PARA REDUCIR NOX. SE PRESENTAN TAMBIEN ALGUNOS ASPECTOS DE UN SISTEMA DE CONTROL AUTOMATICO.
