METHODS AND SYSTEMS FOR REDUCING EMISSIONS OF NITROGEN OXIDES FROM RIBBON BURNERS

摘要

Methods and systems for improving burner, particularly ribbon burner performance, involving admixing a portion of the combustion products from the flue gas resulting from the burner to at least one of a primary and a secondary oxidizer supply to the burner. Admixing a portion of a carbon dioxide-containing flue gas combustion product formed upon combustion of a fuel gas by a ribbon burner significantly reduces NOx emissions resulting from operation of the burner.

主权项

1. A method for reducing emissions of nitrogen oxides from a burner that upon combustion operation forms a flue gas including combustion products, said method comprising:
admixing a portion of flue gas combustion products to at least one of a primary and a secondary oxidizer supply to the burner.
