For the air swirl disc design in front of the burner, should we focus on the natural gas flow rate or the flow velocity? To ensure successful ignition
Are you referring to the swirl chamber outside the burner? It is designed to facilitate uniform mixing of air and fuel gas for complete combustion; there are no particular requirements regarding natural gas
I’m referring to that thing with many nozzles on it, from which natural gas is sprayed out and mixed with air
May I ask, when designing burners, low-load and high-load conditions are taken into account; does the so-called load variation refer to changes in the volumetric flow rate of natural gas? And to ensure stable combustion when the load changes, is it sufficient to just adjust the air supply amount?
The burner design is based on maximum load conditions; stable combustion requires adjusting both the air volume and negative pressure, with both being important.
