How can gas-fired industrial boilers achieve low-NOx emission?

11 Dec 2020

Gas-fired industrial boilers are high-efficiency, eco-friendly and energy-saving, and they play an important role in the production-oriented enterprises. Due to strict requirements for pollutant emissions, enterprises often attach great importance to the emission performance of boilers.

The methods for gas-fired industrial boilers to achieve low-NOx emission

Above all, choose the high-quality fuel, reduce the nitrogen content in the fuel and ensure that the fuel calorific value meets the specified requirements.

Then, adopt the low-NOx combustion technology to control the combustion temperature, oxygen amount and time. The main methods include pure oxygen combustion and temperature control technology (air staging, fuel staging, bulky combustion, flue gas internal circulation, flue gas external circulation, air cooling, water cooling, etc.)

Finally, add the treatment equipment for flue gas emission, such as flue gas denitration technology (SNCR, SCR), AO dry desulfurization and denitrification technology, biomass algae capture technology, etc.
