Due to the progress of The Times, people's awareness of environmental protection, more and more burner enterprises realize that the exhaust emission of the burner is a big problem, so the transformation of the burner has been put on the agenda, therefore, the low NOx burner came into being.
Compared to "back-end" solutions (SCR or SNCR), burners have a lower overall installation cost and do not incur the recurring cost burden of reagent injection and catalyst replacement.
Another advantage of low NOx burners is that they do not have to bear additional space/piping requirements, which is usually associated with SCR.
Of course, there are significant differences between low NOx and many existing burners - in terms of fuel, design requirements, control requirements, flame shape, etc.When these are in front of you, instead of installing a new burner, it is cheaper and more convenient to retrofit it.
