NOx Control Technologies

Description

The combustion of fossil fuels generates NOx, which is a criteria air pollutant. JET offers SCR, SNCR and low-NOx combustion technologies for NOx control. Depending on the specific requirements of the project, we can also provide integrated SCR+SNCR technology which has an excellent cost-performance ratio.

For a typical SCR process, the SCR reactor is installed between the economizer and the air reheater. The following figure shows the process flow:

In the SNCR process, a reducing agent is injected into the boiler where the temperature of the flue gas is between 800 and 1100 ℃ (1472 and 2012°F). The reducing agent reacts with NOx and produce N2 and H2O without the presence of catalyst. The reductant can be anhydrous ammonia, aqueous ammonia or urea. The following figure shows the process flow:
