Abstract (en)

[origin: WO2009091115A2] Provided is a Bunsen burner which can reduce pollutant materials generated during combustion by adopting a lean-rich combustion type, thereby enhancing combustion stability. The Bunsen burner includes a plurality of burner bodies including: a venturi plate having a venturi hole formed therein such that a gas mixture in which a portion of air supplied from a fan is mixed as primary air with fuel jetted from a nozzle unit is introduced, a guide plate for guidings the introduced gas mixture upward, an inclined portion having a plurality of first flame holes for jetting the gas mixture at a predetermined angle with respect to the vertical direction, a side portion that extends downward from a lower side of the inclined portion and has a plurality of through-holes formed therein such that some of the gas mixture passes, and a connection plate having both ends connected to the side portions of the burner bodies, respectively, and having a plurality of second flame holes in which the gas mixture passing through the through-holes and secondary air introduced by the fan and supplied along outer surfaces of the burner bodies are mixed so that lean combustion occurs.
