Application of AdBlue® technology in industrial boiler emission reduction

The application of AdBlue® technology in industrial boiler emission control is mainly based on the selective catalytic reduction (SCR) system. The SCR system reduces nitrogen oxide (NOx) emissions by injecting AdBlue®, a urea aqueous solution, into the flue gas discharged from the boiler. The urea in AdBlue® decomposes into ammonia and carbon dioxide at high temperatures. The ammonia then reacts chemically with the nitrogen oxides in the flue gas under the action of the catalyst, converting them into nitrogen and water vapor, both of which are relatively harmless to the environment.

The working principle of the SCR system is that AdBlue® is atomized in the flue gas discharged from the boiler through a precisely controlled nozzle and then mixed with the flue gas. This mixture then flows through the SCR reactor equipped with a catalyst and undergoes a reduction reaction within a suitable temperature range (usually 300-400°C). The role of the catalyst is to reduce the activation energy of the reaction, thereby achieving efficient NOx conversion at a lower temperature.

The advantage of SCR technology is that it can significantly reduce nitrogen oxide emissions, usually achieving an emission reduction efficiency of more than 85%. In addition, compared with other denitrification technologies (such as selective non-catalytic reduction SNCR), the SCR system can work effectively in a wider temperature window and has a lower ammonia escape rate, thereby reducing secondary pollution to the environment.

In industrial applications, the design and implementation of the SCR system need to consider the specific operating conditions of the boiler, fuel type, emission standards, and the economy and reliability of the system. The system design must also ensure accurate control of the AdBlue® supply and injection system to optimize the denitrification effect and reduce operating costs.

In summary, AdBlue® technology provides an effective solution for achieving strict nitrogen oxide emission standards through the application of SCR systems in industrial boilers, which helps to reduce air pollution and improve environmental quality.
