SCR for NOx reductions

SCR for NOx reductions

SCR for NOx reductions

Any information about the NOx reduction method use in the power industry for simple, combined cycle, fossil or nuclear application.

RE: SCR for NOx reductions

I work with Siemens V94.2 Gas Turbines at a combined cycle gas turbine power station, they control the NOx levels by using a hybrid gas burners. The GT starts up in diffusion burner mode for a stable flame (this flame has hots spots leading to high NOx levels, Once above a certain gas outlet temp the burners change to Pre-mix burner mode ( mixing the air with the gas at the burner), this flame has a much more even temperature but does require a pilot gas supply due to the flame in-stability. In pre-mix mode the NOx levels are greatly reduced.
On some machine they inject steam into the exhaust to reduce NOx.
