The simplest and most effective method to reduce nitrogen oxide emissions in coal-fired fluidized bed boilers
Thread Content
It can be solved by adjusting the combustion process without having to use denitration equipment. I’m hoping some expert can share their knowledge on this; waiting online: handshake
Low-nitrogen combustion modification combined with OFA can significantly reduce NOx concentrations; however, the NOx levels after such treatment may still be above the emission limits. Nonetheless, some small boilers can meet emission standards without additional denitrification equipment when operating at low loads and using high-quality fuel.
In other words, it’s segmental combustion; all that’s needed is to add a secondary air inlet
It reduces nitrogen oxides but increases carbon monoxide; it is not a permanent solution. In the future, when the country regulates carbon emissions, further modifications will still be necessary
