Abstract

PURPOSE: To provide the subject process and device wherein a required minimum quantity of a NOx reducing agent is computed in a combustion system gaseous wate system from the gaseous waste initial NOx concentration, gas temperature and a target NOx concentration in the final denitration gas, thereby preventing unuseful use of the reducing agent.
