Reactor Apparatus and Method for Reducing NOx from Exhaust Gases Produced by Industrial Processes

An apparatus for treating exhaust gases produced by industrial processes and removing or reducing NOx, CO, carbon particulates and hydrocarbons therefrom, said apparatus comprising:

• a reactor including:
• an inlet plenum receiving the exhaust gases;
• a reaction chamber wherein a reaction takes place for treating the exhaust gases;
• an outlet plenum receiving the treated exhaust gases;
• a heat exchanger including a first exchanger chamber between the inlet plenum and an entrance to the reaction chamber and a second exchanger chamber between an exit from the reaction chamber and the outlet plenum:
• wherein exhaust gases exiting the reaction chamber and traveling through the second exchanger chamber and to the outlet plenum are used to heat the exhaust gases traveling from the inlet plenum through the first exchanger chamber and entering the reaction chamber;
• and,
• wherein treated exhaust gas is recirculated from the outlet plenum to the reaction chamber entrance.
