1.4 Natural Gas Combustion - US EPA

Sep 26, 2018 · For large boilers (1MW and above), typical NO x levels are currently likely to be above 70 mg·kWh – ¹ – although it is difficult to be specific because there are many combinations of boiler and burner, with the actual levels being influenced by combustion chamber, burner head and flame type, and geometry.. Flue gas recirculation. The flame temperature may be reduced – and so lessen NO

What Your Boiler Pressure Should Be When It's Heated

Oct 02, 2020 · Normal boiler pressure should be between about 1-2 bars. The ideal boiler pressure is often marked as a range in green on the gauge itself. With red indicating the low and high boiler pressure zones. Bear in mind that your boiler may continue to work if the pressure is in these red zones.
