In industrial processes, it is very common to use boilers for material processing, but in this process, nitrogen is oxidized at high temperatures to form nitrogen oxides, such as nitric oxide and nitrogen dioxide. This process is mainly related to temperature and oxygen concentration, so the higher the combustion temperature and the greater the oxygen concentration, the more nitrogen oxides are generated.
So what to do with the nitrogen oxides produced by the boiler?We recommend using the following methods to achieve NOx compliance.
1.Nitrogen oxide treatment agent. The nitrogen oxide treatment agent launched by Fersa Biopharma comprehensively uses enzyme catalytic technology, polymer capture technology and absorption and fixation technology, which can effectively catalyze the decomposition and absorption of nitrogen oxides in the air, and is suitable for nitrogen oxide (NOx) treatment in the atmosphere, industrial parks, factories and other environments, and can be used with fog cannon trucks, drones, spray systems, etc., to significantly reduce the concentration of nitrogen oxides in the exhaust gas.
2.Low-nitrogen combustion technology. Reduced combustion temperature and oxygen concentration by improving combustion or using low-nitrogen burners, thereby reducing the generation of nitrogen oxides. This technique often needs to be carried out in boiler design and retrofits.
3.Flue gas denitrification technology. A denitrifier is added to the flue at the tail of the boiler to cause the nitrogen oxides that have been generated to react with the denitrifier and convert them into harmless nitrogen and water vapor. Common denitrification agents are ammonia and urea. This technique requires additions and treatments during boiler operation.
4.Exhaust gas recirculation technology. Part of the tail flue gas is returned to the combustion chamber to reduce the oxygen concentration and combustion temperature, thereby reducing the formation of nitrogen oxides. This technique needs to be carried out in boiler design and retrofit.
It is worth noting that different treatment methods are suitable for different boiler types and emission standards, and it is necessary to choose the appropriate method for treatment according to the actual situation.
