PAPER OPEN ACCESS Discussion on the key technology of

(5) NITROGEN OXIDES means the sum of nitric oxide and nitrogen dioxide in the flue gas, collectively expressed as nitrogen dioxide and averaged over a period of 15 consecutive minutes. (6) COMBUSTION MODIFICATION means any modification of the burner, combustion air flow, or fuel flow system that reduces nitrogen oxides emissions.

Influence of retrofitting of low nitrogen burner on coking

Aug 14, 2020 · The modification of low-nitrogen burner adjusted the air distribution mode and adopted the low-nitrogen combustion technology of air classification. The excess coefficient of air in the main burning area was kept at about 0.85, forming the under-oxygen combustion, making the temperature of the main burning area lower than before the modification, thus reducing the proportion of molten or …

1.3 Fuel Oil Combustion - US EPA

Jul 21, 2000 · Combustion modification is generally the lowest cost NOx control method available, in particular retrofitting low NOx burners, and they have been retrofitted to many utility boilers. However, low NOx burners cannot be applied to all types of combustion systems and seldom achieve the NOx reductions required by the latest SIP Call requirements.
