Numerical Simulation Of De-Nox By Reburning Of Waste Tire Pyrolysis Gases

The possibility of gases from waste tire pyrolysis as the reburning fuel is discussed. Based on GRI3.0 and the methods, of Gear, the calculations of De-NO,, by reburning of waste tire pyrolysis gases are presented. The main components of gases from waste tire pyrolysis are identified as H-2, CO, CO2, CH4, C2H4 and C2H6. The results show that the reducing efficiency for NO,, reduction by reburning of waste tire: pyrolysis is about 40%. H, OH and O are three important free radicals which are necessary to start a series of important radical reactions. HCN and NH3 play an important role in the reburning system.
