This application claims priority to Chinese application no. 202321763983.5, filed on Jul. 6, 2023, the entire contents of which are incorporated by reference herein.
The present disclosure relates to the technical field of burners, and relates specifically to a burner for a gaseous fuel-burning fireplace.
In recent years, fireplaces having dual functions of decoration and heating have become increasingly popular, especially real-fire gas fireplaces and real-fire alcohol fireplaces which have become a first choice for decoration and heating in the home due to their clean and hygienic use, stable combustion, and high thermal efficiency utilization. In order to make combustion sufficient and easy to control in real-fire alcohol fireplaces, generally, a liquid alcohol fuel is vaporized and then introduced into a burner for combustion.
However, basically all of the burners for burning gaseous fuel currently available on the market have flames directly burning on metallic burners, or have an elongated shape or a circular shape. The burners are flat, the flames are relatively rigid and insufficiently lively, and there is no graduated feeling. Furthermore, there is a lack of decoration of simulated solid fuels and lack of harmonious correspondence between flames and fuels, and there is an unnatural feeling that flames appear out of nowhere. Even if a mode in which a plurality of burners are combined to form a flame appears on the market, it is necessary to separately introduce gaseous fuel for combustion. The structure is complicated, and the installation is complicated.
The problem to be solved by the present disclosure is to provide a burner for burning gaseous fuel, so as to overcome the problem of rigid and insufficient flames in the prior art, and to provide a three-dimensional flame shape and give users more visual enjoyment.
In order to solve the technical problem, the present disclosure provides a burner for burning gaseous fuel, comprising a gas intake port, several horizontal portions, and several inclined portions, one end of each of the horizontal portions being connected, and one end of each inclined portion located at a lower position being connected and fixed to the other end of a horizontal portion; the horizontal portions and the inclined portions each have an internally hollow structure and communicate with each other, the inclined portions are inclined upwardly at an angle La with respect to the horizontal portions, and the inclined portions and the horizontal portions are combined into the shape of a three-dimensional geometric space; the gas intake port is provided on bottom surfaces of the horizontal portions and communicates with the interior of the horizontal portions, and gaseous fuel may enter the interior of the horizontal portions from the gas intake port and further diffuse into the interior of the inclined portions; and the horizontal portions are provided with a plurality of first flame holes, and the inclined portions are provided with a plurality of second flame holes.
Further, the upwardly inclined angle ∠α of each of the inclined portions (3) may be the same or different, where ∠α is 20° to 80°.
Further, lower surfaces of the horizontal portions each have an upwardly inclined angle ∠β, where ∠β is 1° to 10°.
Further, the burner further comprises several simulated solid fuels, wherein the simulated solid fuels are provided with textures and colors simulating real solid fuels, and the simulated solid fuels are fastened to the inclined portions.
Further, the inclined portions are provided with supporting surfaces which may be used to support the simulated solid fuels.
Further, when two horizontal portions are provided, the two horizontal portions may be arranged opposite to each other and connected to each other so as to form one body.
Further, the number of horizontal portions is greater than or equal to three, and the burner for burning gaseous fuel according to the present disclosure further comprises a combustion chamber main body connecting all the horizontal portions together, wherein the combustion chamber main body has a hollow structure and is provided in the middle of all the horizontal portions, the horizontal portions are arranged around the circumference of the combustion chamber main body, and spacing between any two of the horizontal portions may be the same or different; the gas intake port is provided in a bottom surface of the combustion chamber main body, the gas intake port communicates with an interior of the combustion chamber main body, and the interior of the combustion chamber main body communicates with the interior of the horizontal portions; and the combustion chamber main body is provided with a plurality of third flame holes.
Further, the combustion chamber main body is provided with several combustion air inlets through which combustion air can be supplemented for a middle region of the burner.
Further, upper surfaces of the combustion air inlets are higher than an upper surface of the combustion chamber main body.
Further, when the burner is mounted on a product, the bottom of the burner may be provided with pebbles and/or crystal stones and/or crushed glass and/or simulated charcoal beds and simulated solid fuels for decoration, which are used to simulate the structure of a carbon bed after a real solid fuel is burned and may cover the combustion chamber main body and/or the horizontal portions, so that it looks more beautiful and realistic as a whole.
In the above technical solutions, the term “several” means one or more than one.
During the operation of the present disclosure, gaseous fuel or the fuel obtained by gasifying liquid fuel is introduced into the interior of the burner through the gas intake port, diffused into the combustion chamber main body and/or the interior of the horizontal portions and the inclined portions, and further emitted from the first flame holes, the second flame holes and the third flame holes. Then, when flames are ignited, the flames are burning on each of the combustion chamber main body and/or the horizontal portions and the inclined portions, thereby forming a flame effect in a three-dimensional (3D) form. Moreover, the combustion air inlets may be used to supplement the middle region of the burner with air required for combustion, so that the combustion is more complete and the flames are brighter.
In addition, the simulated solid fuels are provided on the inclined portions, so that the flames are more realistic like real firewood burning in a bonfire, which is warm and comfortable.
Compared with the prior art, the advantageous effects of the present disclosure are as follows:
In the burner for burning gaseous fuel provided by the present disclosure, since the inclined portions inclined upwardly are provided, the inclined portions, the horizontal portions, and/or the combustion chamber main body form three dimensional flames in a 3D space, the bonfire effect of real firewood burning can even be imitated, and the decorative effect of the flames is stronger, with better visual appreciation. Moreover, the burner has a simple structure and is easy for installation.
The names of the components corresponding to the respective reference numerals in the figures are as follows:
1—gas intake port; 2—horizontal portion; 21—first flame hole; 3—inclined portion; 31—second flame hole; 32—supporting surface; 4—combustion chamber main body; 41—third flame hole; 42—combustion air inlet; 5—simulated solid fuel; 6—pebble.
