LOW-NOISE, PREMIXING BURNER

摘要

The present invention relates to a low-noise, premixing burner which prevents resonance-based noise generation during combustion by having an improved flame hole structure. According to the premixing burner of the present invention, which mixes gas with air in advance for combustion, a burner body is formed by overlapping a plurality of partially cut plates, and the plates are arranged such that the cut parts of the adjoining plates cross each other while forming a mixed gas passage and a plurality of flame holes. The flame holes formed at the upper portion of the burner body have different sizes.
