Burner devices are used in household cooking appliances, boilers, and industrial facilities, and gas is generally used as fuel for burner devices.

Burner devices may be divided into single burner devices using one burner and dual burner devices using two or more burners. Dual burner devices are usually composed of an outer burner formed in a circular shape and an inner burner disposed inside the outer burner.

Furthermore, there are also known stack burner devices that are constructed by stacking burners that can provide a simmer flame and a main flame, respectively.

However, these conventional burner devices have a problem in that a flame stabilization function that maintains the stability of a flame by preventing the flame from being extinguished is poor.

In particular, dual stack burner devices in which an outer burner and an inner burner are constructed as a stack have a problem in that it is difficult to dispose a structure for providing a flame stabilization function due to the complex configuration of the dual stack burner devices.
