The Influence of Low Nitrogen Combustion Technology on Boilers

The Influence of Low Nitrogen Combustion Technology on Boilers
In recent years, low nitrogen combustion technology has been widely applied in burner manufacturers. It reduces the emission of nitrogen oxides by changing the combustion conditions of the combustion equipment, and utilizes a portion of low-temperature flue gas to return to the combustion zone with lower oxygen content, thereby reducing the temperature and oxygen concentration of the combustion zone and inhibiting the production of nitrogen oxides.
A new low nitrogen conversion standard has been established, and the nitrogen content emission standard for Beijing Petroleum (Gas) boilers will require reaching this standard before July 1, 2017. It is expected that nitrogen oxide emissions will be lower in the future. Low nitrogen combustion technology will also be applied to various industries with combustion equipment, and low nitrogen combustion technology will also be greatly improved.
The impact of low nitrogen burners on boiler operation is mainly influenced by boiler design and the quality of coal used. Through combustion adjustment, secondary air ratio, and SOFA air ratio, the steam temperature parameters of some factories have basically reached the design values, and the combustible matter of fly ash has significantly decreased. Secondly, after the transformation of the low nitrogen burner, the changes in the temperature field inside the furnace will have a significant impact on the flue gas temperature and steam temperature characteristics at the furnace mouth. The scaling and slagging of the water wall will be greatly improved, the heat absorption of the water wall in the boiler will increase, the flue gas temperature at the furnace outlet will drop, and the Superheated steam temperature and reheated steam temperature of the boiler will drop. The changes in boiler steam temperature characteristics after low nitrogen combustion reforming are mainly influenced by the above two factors. Which factor dominates depends on the design of the boiler and the quality of the coal used.
