A gas stove is mainly composed of structural components such as the stove surface, fire cover, stove head, stove frame, valve body, control components, and pipelines. As one of the core components of a gas stove, the burner is related to its firepower, safety, and service life. The materials of furnace heads are mainly divided into four common types: cast iron furnace heads, ceramic furnace heads, aluminum furnace heads, and iron furnace heads.

The stove head includes a stove head base and a stove head fire cover. The base mainly plays a role in evenly distributing gas, while the fire cover has several fire holes on it, mainly supporting flame combustion. Due to the high surface temperature of the flame, the flame cover is one of the more important components in the furnace head.
