In simulated flue gas, NO reduction by methane over iron oxides could exceed 95% when the temperature was above 900 °C at fuel rich condition. 1.17% methane could continuously reduce NO over 100 h at 1050 °C in simulated flue gas which contained 2.0% O 2, 16.8% CO 2 and 0.05% NO balanced by N 2.
applying urea is usually done in ranging from 950 °C to 1,050 °C (European IPPC Bureau, 2014). Urea reacts with NO. x. contained in flue gas. The most amount of NO. x. ... Thanks to this change, the reducing agent gets in lower flue gas temperature and achieves better conversion of chemical reaction.

Exhaust gas temperature 1050° C. An engineering challenge. Published: Sept. 2000. Introduction . The European Automobile Manufacturers Association EAMA has made an obligation to reduce the average carbon dioxide emissions in new vehicles to 140 g/km by the year 2008.
Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.
The SNCR is the simplest and most economical form of NOx-reducing technology and is best suited for applications where a modest NOx reduction of 30-40% is required together with tight schedules and limited plot space where the ﬂue gas temperatures are high …

Isothermal reduction of haematite carbon mixtures was investigated at temperatures 750–1100°C under inert atmosphere. Mass loss curves proved the stepwise reduction of haematite to metallic iron. The non-linear feature of haematite to magnetite reduction kinetics was observed and an activation energy of 209 kJ mol−1 was calculated.
