Problems solved by technology

When burning, in the limited space of the straight cylindrical shape of the inner shell, the space that was originally filled by the airflow blown from the lower layer is blown into the upper airflow, and the collision between the airflows is more intense, and the airflows push and cancel each other. The strong flow will cause a lot of combustion noise, and the strong turbulent flow will offset the strength of the airflow ejected from the barrel mouth, resulting in insufficient flame height and insufficient firepower of the gas stove

Embodiment Construction

[0010] Such as figure 1 As shown, a burner with low noise and strong firepower includes a cylindrical outer shell 1 and a cylindrical inner shell 2, the inner shell 2 is set inside the outer shell 1, the top of the outer shell 1 and the top of the inner shell 2 are closed and connected, and the outer shell 1 A sandwich cavity is formed between the inner shell 2, the bottom of the outer shell 1 is provided with an air inlet 11, the bottom 21 of the inner shell 2 is sealed, and the inner cavity of the inner shell 2 is set to be at least two or more stages enlarged step by step from bottom to top. The above steps are in the shape of steps, and the side walls in the length direction of each step are provided with ventilation holes 22 all over. Specifically, the stepped inner cavity of the inner shell 2 is arranged in three stages, and the number of ventilation holes 22 in each stage increases step by step from bottom to top.

[0011] In this embodiment, the side wall of the outer...

Abstract

The invention discloses a low-noise high-firepower combustor which comprises a cylindrical outer shell and a cylindrical inner shell sleeved in the outer shell. The top of the outer shell and the top of the inner shell are in closed connection, an interlayer cavity is formed between the outer shell and the inner shell, an air inlet is formed in the bottom of the outer shell, the bottom of the inner shell is sealed, an inner cavity of the inner shell is provided with at least two or more steps gradually enlarged from bottom to top, and the lengthwise side wall of each step is provided with widespread vent holes. Airflow blown out of a bottom cavity is ejected outwards from the space corresponding to the bottom cavity, airflow blown out of each cavity above the bottom cavity can be ejected outwards from the enlarged space corresponding to the cavity, collision and pushing of the airflow of the steps at different heights are much weakened as compared with traditional collision and pushing, turbulence can be effectively reduced, and offset of the ejection force of the airflow ejected out of the combustor from the steps at different heights can also be effectively weakened.

Description

technical field [0001] The invention relates to the technical field of burners. Background technique [0002] Gas stoves used in some professional kitchens such as the catering industry are often equipped with a blower in order to increase the firepower. The burner connected to the fan consists of a cylindrical outer shell and an inner shell, the inner shell is set inside the outer shell, and the top of the outer shell and the inner shell There is a closed connection between them, and a sandwich cavity is formed between the outer shell and the inner shell. The bottom of the outer shell is provided with an air inlet, the bottom of the inner shell is sealed, and the side wall of the inner shell is provided with vent holes all over. At present, the inner shell is used as a furnace cavity for combustion, and no matter what kind of burner it is, the inner shell is all set into a straight cylindrical shape. The way of mixing gas is divided into gas mixing inside the furnace cavit...
