Description

Commercial premixing burner fire hole

Technical Field

The utility model relates to the technical field of burners, in particular to a commercial premixing burner fire hole.

Background

The gas cooker is a kitchen utensil which is heated by direct fire by using liquefied petroleum gas (liquid state), artificial gas, natural gas and other gas fuels. Gas stoves, also called stove plates, are increasingly used with the improvement of living standard. The premixed burner, also called a breeze energy-saving burner, is characterized in that the fuel gas is mixed with air in advance according to a proportion and then sprayed out for combustion, the thermal efficiency is high and generally exceeds more than 24%, and the premixed burner is widely favored by people along with the proposal of the existing energy-saving and emission-reducing concepts, and the utilization rate is also higher and higher.

The fire cover of the existing premixing furnace end is a fire hole uniformly and annularly arranged on the inner wall of the fire cover, and is easy to cross-burn with central flame during combustion, and the central flame is insufficient in air, so that insufficient gas combustion is caused.

Disclosure of Invention

The utility model aims at solving the problems, and the aim is to provide a fire hole of a commercial premixing furnace end, which is crossly impacted after being sprayed, has stronger combustion reaction, shorter flame and better heat exchange.

The utility model provides a commercial premixed burner fire hole, which comprises a burner body, a fire cover arranged on the burner body and a plurality of groups of fire holes uniformly distributed on the fire cover, wherein each group of fire holes comprises two or three fire holes, the central lines of the two or three fire holes are arranged in a crossing way, and mixed gas is sprayed out of the fire holes and then is in cross collision.

Preferably, the center lines of the two or three fire holes intersect at an angle of 5 DEG to 15 deg.

Preferably, the central lines of the two or three fire holes form a first intersection point, and the distance between the first intersection point and the center of the burner body is 5-20mm.

Preferably, the fire cover is a split fire cover.

Preferably, the fire hole is upper spraying, inner spraying, outer spraying, inclined spraying or a combination thereof.

Preferably, the central lines of the fire holes in adjacent groups intersect to form a second intersection point, and the second intersection point is arranged in a deviated manner from the center of the burner body.

Preferably, the spraying directions of the plurality of groups of fire holes are arranged in a left-handed or right-handed mode.

Preferably, the fire hole is a round hole, a strip hole, a triangular hole, a semicircular hole or a corrugated hole.

Preferably, the fire hole is internally nested with a corrugated belt.

The utility model has the advantages and beneficial effects that:

the utility model provides a commercial premixed burner fire hole, which comprises a burner body, a fire cover arranged on the burner body and a plurality of groups of fire holes uniformly distributed on the fire cover, wherein each group of fire holes comprises two or three fire holes, the central lines of the two or three fire holes are arranged in a crossing way, and mixed gas is sprayed out of the fire holes and then is in cross collision. After each group of adjacent fire holes are sprayed out, the fire holes are crossed and impacted at a certain angle, so that the combustion reaction is more intense, the flame is shorter, and the heat exchange is better.

Detailed Description

Referring to fig. 1-3, the utility model provides a commercial premixed burner fire hole, which comprises a burner body, a fire cover 1 arranged on the burner body and a plurality of groups of fire holes 2 uniformly distributed on the fire cover 1, wherein each group of fire holes 2 comprises two or three fire holes 2, the central lines of the two or three fire holes 2 are arranged in a crossing way, mixed gas is ejected from the fire holes 2 and then collides with each other in a crossing way, the combustion reaction is more intense, the flame is shorter, and the heat exchange is better.

In one embodiment, the center lines of two or three fire holes 2 intersect at an angle α, which is 5 ° -15 °.

In one embodiment, the center lines of the two or three fire holes 2 form a first intersection point 3, and the distance between the first intersection point 3 and the center of the burner body is L, and the length of L is 5-20mm.

In one embodiment, the fire cover 1 is a split fire cover 1.

In one embodiment, the fire hole 2 is an upper spray, an inner spray, an outer spray, an inclined spray, or a combination thereof. When the fire holes 2 are in upper spraying, the fire holes 2 are arranged at the top of the fire cover, each group of fire holes 2 comprises two or three, and the central lines of the two or three fire holes 2 are arranged in a crossing manner.

In one embodiment, the center lines of the adjacent fire holes 2 intersect to form a second intersection point 4, and the second intersection point 4 is offset from the center of the burner body. The spraying directions of the fire holes 2 are arranged in a left-handed or right-handed way. The natural gas sprayed from the fire hole 2 is impacted in a cross way, a left-handed or right-handed space is formed in the center of the burner body, combustion is more complete, and heat exchange is better.
