Description

An upside-down steak oven burner

technical field

The utility model relates to a combustion device, in particular to an upside-down steak oven burner.

Background technique

Now the grilled steak is grilled with a burner. Since the existing burner works with the ceramic oven bag facing upwards, when the steak is grilled, the fat in the beef will drip to the point of burning. In the burner, it not only pollutes the burner, but also easily causes the burner to be blocked, thereby causing uneven firepower. If the existing burner is inverted, that is, the ceramic furnace bag is facing down, the burner is located above the steak, and the steak is burned downward. Because the split piece of the existing burner is in the form of a binary mixed structure with a middle partial flow, the split flow is insufficient, and the thermal efficiency is less than 60%. If it is inverted, the phenomenon of tempering and deflagration will occur. Therefore, developing an upside-down steak burner has become an urgent problem to be solved by those skilled in the art.
