Reducing Harmful Emissions of Nitrogen Oxides Via the Partial Recirculation of Flue Gases Into the Combustion Chamber of Oil Refinery Furnaces

The article presents the results of theoretical and experimental studies to justify the application of the partial recirculation of flue gases into the combustion chamber of operating oil refinery furnaces to reduce nitrogen oxide emissions. Recommendations for the use of this method in various tube furnace designs are proposed. Moreover, new technical solutions are proposed for the development of an improved installation for burning liquid fuel in the form of water–oil emulsion, and a burner device of the GP-2 type in which recycled gases are supplied to the combustion zone is proposed for implementation.
