Problems solved by technology

However, flashback can occur when combustion is performed in the low load region
In addition, when the load is increased, the gas flow rate of the gas mixture increases, forming an unstable flame

Abstract

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.

Description

technical field [0001] The present invention relates to a Bunsen burner using a lean-rich type, and more particularly, to a Bunsen burner capable of reducing pollutants generated during combustion by employing a lean-rich type burner, thereby improving combustion stability. Background technique [0002] Generally, combustion types of gaseous fuels are classified into premixed combustion types, diffusion combustion types, and partial premixed combustion types. In premixed combustion types, gaseous fuel and combustion air are premixed before being provided to the combustion chamber. In the diffusion combustion type, fuel and air are supplied separately. In the partially premixed combustion type, the premixed combustion type and the diffusion combustion type are mixed. [0003] Partially premixed combustion is performed by a Bunsen burner. The Bunsen burner premixes the fuel with some of the air required for combustion as primary air and then provides the gas mixture. In a...
