Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.
The first embodiment is as follows:
referring to fig. 1-3, the present invention provides a fire cover for a burner, comprising an annular main body 1, wherein the annular main body 1 comprises an inner sidewall 11, an outer sidewall 12 and a top wall 13, wherein the top wall 13 is connected between the top of the inner sidewall 11 and the top of the outer sidewall 12, a gas groove 14 with a downward opening is formed between the inner sidewall 11, the outer sidewall 12 and the top wall 13, and is characterized in that: lateral wall 12 includes along circumference interval distribution and a plurality of beads 15 that connect gradually, bead 15 from top to bottom slope sets up, makes the fire lid form the profile gear shape be equipped with fire hole 16 on bead 15, fire hole 16 with gas groove 14 intercommunication. Bead 15 is from top to bottom slope setting, and fire hole 16 sets up on bead 15, the shape of fire hole 16 positions can make flame produce the rotation of certain direction for the slope distortion for combustion area is big, thereby makes combustion efficiency high, has effectively improved the availability factor of gas, has not only practiced thrift the resource, and has satisfied people's user demand.
The rib 15 has a first side 151 facing downward and a second side 152 facing upward, the fire holes 16 are disposed on the first side 151, the fire holes 16 are disposed on the same side, the flame is sprayed out from the fire holes 16 on one side, so that the generated flame is sprayed out in a certain direction, and the number of the fire holes 16 disposed on the first side 151 is at least 2. In this embodiment, the number of the fire holes 16 on the first side 151 is two. The fire holes 16 may be circular, oval, square, or other shapes.
The total number of the fire holes 16 is 170-190, the number of the fire holes 16 in the embodiment is 180, and is 16 more than that of the traditional furnace end fire holes 16, the number of the fire holes 16 on the fire cover is increased, and the combustion load is increased.
The convex ribs 15 are distributed at equal intervals along the circumferential direction, so that the combustion at each position on the fire cover is uniform. The cross section of the rib 15 is wedge-shaped. And a hollow ignition groove 17 is formed on the inner side of the convex rib 15 and is used for communicating the fire hole 16 with the gas groove 14, so that gas is fully contacted and mixed with air, the gas is fully combusted, and the combustion efficiency is improved.
