Reactor air supply system and burner configuration

A reactor air supply system comprising:

• a first air inlet configured to receive air supplied from a first air supply;
• a burner including a burner nozzle configured to discharge fuel for mixing with the first air and configured to ignite the fuel/air mixture;
• a second air inlet configured to receive heated air supplied from a second air supply and heated by a heat source;
• and
• a duct with a first inlet configured to receive the ignited fuel/air mixture from the burner and a second inlet configured to receive the heated air supplied from the second air supply, the duct having an outlet configured to connect to a reactor,
• wherein the duct is configured to receive the heated air from the second air supply such that the heated air mixes with the ignited fuel/air mixture at a location downstream of the burner, and
• wherein the heat source is separated from the burner.

A method of supplying air to a reactor having a first reaction section, the method comprising:

• providing a first air supply for supplying a first air;
• providing a burner including a burner nozzle for discharging fuel for mixing with the first air and for igniting the fuel/air mixture;
• providing a second air supply for supplying a heated second air heated by a heat source;
• and
• providing a duct with a first inlet for receiving the ignited fuel/air mixture from the burner and a second inlet configured to receive the heated second air, the duct having an outlet connected to the first reaction section,
• wherein the duct receives the heated second air such that the heated second air mixes with the ignited fuel/air mixture at a location downstream of the burner, and
• wherein the heat source is separated from the burner.
