- the present invention relates to a salt hole arrangement structure of a premixed burner made of a plate, and more particularly, to a structure in which a burner body portion and a salt hole are positioned to cross each other to absorb a deformation due to thermal expansion due to accumulation of combustion heat, thereby fixing the burner.
- the present invention relates to a salt hole arrangement of a premixed burner composed of a sheet material which can prevent a large force from being applied and extend the burner's endurance life.
- a gas burner used in a combustion device such as a boiler or a water heater may be classified into a Bunsen burner and a pre-mixed burner according to a method of mixing combustion gas and air.
- the Bunsen burner is a burner that supplies the minimum primary air necessary for combustion from the nozzle injecting the gas and supplies the excess secondary air to the part where the flame is formed to realize complete combustion, and has excellent combustion stability. On the other hand, since the flame is formed by the secondary air, the flame length is long.
- the premix burner burns the premixed gas pre-mixed with the combustion gas and air in the mixing chamber, enabling operation at a low air ratio, enabling high efficiency and high load combustion, and reducing the overall flame length.
- the temperature of the flame has the advantage of reducing the generation of pollutants such as carbon monoxide and nitrogen oxides.
- Bunsen burners are mainly used, but in recent years, premixed burners are mainly used to reduce the generation of pollutants and to downsize the combustion chamber.
