METHOD FOR LOW NOx COMBUSTION OF SYNGAS / HUGH HYDROGEN FUELS

A method of achieving low NOx in operation of a non-premixed combustion system comprising:

• a. obtaining a supply of fuel comprising hydrogen gas;
• b. obtaining a supply of air and splitting the supply of air into a first percentage of air and a second percentage of air;
• c. forming a fuel-rich mixture of the fuel and the first percentage of air;
• d. reacting the fuel-rich mixture to produce partial reaction products consisting essentially of reacted fuel and remaining unreacted fuel plus a heat of reaction and transferring a portion of the heat of reaction to the second percentage of air thereby producing a heated second percentage of air and cooled partial reaction products;
• and
• e. combusting the cooled partial reaction products on contact with a stoichiometric portion of the heated second percentage of air in a non-premixed flame such that a second portion of the heated second percentage of air bypasses the non-premixed flame thereby reducing heat liberated in the non-premixed flame.
