Q – My heater has a floor fired heat intensity greater than 300,000 Btu/hr/ft2. Can ClearSign’s core burner technology still meet low NOx emissions?

Q: Q – My heater has a floor fired heat intensity greater than 300,000 Btu/hr/ft2. Can ClearSign’s core burner technology still meet low NOx emissions?

Absolutely, unlike current ultra low NO x burners, ClearSign’s technology does not achieve low NO x emissions solely on flue gas entrainment within the furnace. Due to its well mixed fuel and air stream, the burner generates extremely low NO x . Even with disruptive furnace currents and reduced flue gas recirculation within the furnace, the burners will still produce industry leading NO x emissions.
