Most of current industrial burners are thermo-acoustically unstable, therefore, designing the upstream and downstream sides of the burner is critical to not operating the system at the unstable frequency of the burner. In addition, there is still instability at low gas/air ratio which is needed for reducing NOx and CO2. Moreover, the current burners are not working for different mixture, e.g., CH4/H2.

Our patented idea of merging an ultra-thin broadband muffler at the upstream side of the burner can fully stabilize the burner itself and the technical limits of thermo-acoustically designing of the upstream and downstream sides of the burner will be totally removed. In addition, because of the design parameters that are used for the muffler, it can prevent flash back and it can also function as a flame arrestor.
