Latest Patents

Zawadzki holds a patent for a method titled "Low nitrogen oxides emissions from carbonaceous fuel combustion using three stages of oxidation." This patent outlines a process for reducing NO emissions during the combustion of carbonaceous fuels. The method employs two sequential stages of partial oxidation followed by a final oxidation stage. In the first stage, a substoichiometric air condition of about 0.55 to 0.75 is utilized in a plug flow manner. The second stage combustion occurs at a stoichiometric ratio of approximately 0.80 to 0.99. As the combustion products cool through radiant heat transfer to the boiler furnace walls, overfire air is introduced to achieve a stoichiometric ratio of about 1.05 to 1.25, completing the combustion process. This innovative method effectively reduces the formation of thermal NO.
