Problems solved by technology

The existing technology has the following defects and deficiencies due to the structural setting: 1. Because the gas is not fully mixed with the air, the combustion is insufficient, resulting in waste of resources; 2. The temperature around the flame port is high, and because there is no cooling system, after long-term use, Easy to burn out, resulting in short service life
Therefore, there is a large room for improvement in the current technology

Embodiment 1

[0036] like figure 1 and figure 2 As shown, a gas boiler burner according to the present invention includes a boiler body 1 and a burner body 2, and the two components are arranged in cooperation to form the main structure of the present invention.

[0037] The boiler body 1 includes a boiler shell 11 , a heating cavity 14 is formed in the boiler shell 11 , and a discharge port 12 is provided on the boiler shell 11 , and the discharge port 12 communicates with the heating cavity 14 . In addition, the boiler shell 11 is provided with a first jacket 13, the first jacket 13 is provided with a first water inlet 131 and a first water outlet 132, the first water inlet 131 and the first outlet The nozzles 132 are in airtight communication with the first jacket 13 .

[0038] The burner body 2 includes a burner casing 21 , a cylinder body 22 is arranged on the inner and upper part of the burner casing 21 , a first mixing chamber 24 is formed in the inner and lower part of the burner...

Embodiment 2

[0045] like image 3 and Figure 4 As shown, an air pressurizing chamber 26 is provided below the first mixing chamber 24 in the present invention, the air pressurizing chamber 26 communicates with the air pressurizing device 3 , and the lower end of the air passage 23 communicates with the air pressurizing chamber 26 . Specifically for this embodiment, the first mixing chamber 24 and the air pressurizing chamber 26 become independent chambers, the air pressurizing chamber 26 provides air for the air passage 23 alone, and the first mixing chamber 24 becomes an independent chamber. At this time, the second mixing chamber 222 can be reserved or omitted. When omitted, the pressure-relief baffle 223 is arranged at the lower port of the cylinder 22, that is, the upper and lower sides of the pressure-relief baffle 223 are the combustion chamber 221 and the first A mixing chamber 24, if the air flux in the cylinder 22 needs to be the maximum amount, the pressure-relief baffle 223 is...

Embodiment 3

[0048] like Figure 5 and Image 6 As shown, a plurality of cylindrical bodies 22 are arranged in parallel in the combustor casing 21 of the present invention. Specifically, in this embodiment, the plurality of cylinders 22 are evenly distributed in the burner housing 21 , each cylinder 22 is provided with a plurality of air passages 23 on the periphery, and the second jacket 27 surrounds all the cylinders 22 ; Each cylinder 22 is provided with a combustion chamber 222 , a combustion plate 225 , a pressure reducing baffle 223 , a second mixing chamber 222 , and a second spoiler 226 as in the first embodiment. The arrangement of the plurality of cylinders 22 in this embodiment enables the burner to output relatively balanced heat on a larger section, and the gas pipeline of each cylinder 22 can also be controlled according to the requirement of combustion heat.

[0049] The implementations and principles of other parts of this embodiment are the same as those of the first and...

Abstract

The invention relates to the technical field of burners, in particular to a gas boiler burner. The gas boiler burner comprises a boiler body and a burner body. The boiler body comprises a boiler shell. A heating cavity is formed in the boiler shell. The boiler shell is provided with a discharge port. The discharge port is communicated with the heating cavity. The burner body comprises a burner shell. A cylinder is arranged on the upper portion in the burner shell. A first mixing chamber is formed on the lower portion in the burner shell. A combustion chamber is arranged on the upper portion in the cylinder. A second mixing chamber is arranged on the lower portion in the cylinder. The combustion chamber is communicated with the heating cavity. A combustion plate with a plurality of combustion holes is arranged in the combustion chamber. A plurality of air passages are arranged in the cylinder or on the periphery of the cylinder. The first mixing chamber is connected with a gas pipe and an air boosting device. The burner shell and the boiler shell are connected with each other. The gas boiler burner has the advantages of being reasonable in structural arrangement, long in service life, more sufficient in combustion and the like.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a gas boiler burner. Background technique [0002] The gas boiler burner is a heating device that uses gas as the source material, which is well known and common to people. Existing boiler burners are generally provided with a gas nozzle and an air nozzle near it, the gas and air enter the combustion chamber together, and are mixed and burned in the combustion chamber. The existing technology has the following defects and deficiencies due to the structural arrangement: 1. Because the gas is not fully mixed with the air, the combustion is insufficient, resulting in a waste of resources; 2. The temperature around the flame port is high, and because no cooling system is provided, after long-term use, It is easy to burn out, resulting in a short service life. Therefore, there is a large room for improvement in the current technology. SUMMARY OF THE INVENTION [0003] In order to...
