NOx measurement with natural gas as 100% fuel

Dear experts,

Does anyone has any measurement of stack NOx when the fuel is 100% natural gas?

Please see the attachment from KHD presentation outlining the range of NOx for different kilns and abatement measures which indicates that archiving NOx below 450 mg/Nm3@10%-O2 without SNCR or SCR is not possible. However, these are for kilns using mixed solid and liquid fuels not 100% natural gas. I Iran most kiln run on 100% gas and we have measured NOx well below KHD’s suggested values!

Please share you experience.

Regards;
