Burner for burning gaseous fuel

Abstract

A burner for burning gaseous fuel includes a gas intake port, several horizontal portions, and several inclined portions. One end of each inclined portion located at a lower position is connected and fixed to one end of a horizontal portion, and the other ends of all the horizontal portions are connected to each other either directly or by means of a combustion chamber main body. The horizontal portions, the inclined portions, and the combustion chamber main body are in communication with each other. The inclined portions are inclined with respect to the horizontal portions. The gas intake port is provided at the very bottom of the burner. When a gaseous fuel is introduced and ignited, flames burn in each of the combustion chamber main body, the horizontal portions, and the inclined portions, thereby forming a flame effect in a three-dimensional (3D) form.

1 . A burner for burning gaseous fuel, characterized by: 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 ∠α with respect to the horizontal portions; the gas intake port is provided on bottom surfaces of the horizontal portions and communicates with the interior of the horizontal 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. 
     
     
         2 . The burner for burning gaseous fuel according to  claim 1 , wherein: the upwardly inclined angle ∠α of each of the inclined portions may be the same or different, where ∠α is 20° to 80°. 
     
     
         3 . The burner for burning gaseous fuel according to  claim 1 , wherein: lower surfaces of the horizontal portions each have an upwardly inclined angle ∠β, where ∠β is 1° to 10°. 
     
     
         4 . The burner for burning gaseous fuel according to  claim 1 , wherein: the burner further comprises several simulated solid fuels fastened to the inclined portions. 
     
     
         5 . The burner for burning gaseous fuel according to  claim 4 , wherein: the inclined portions are provided with supporting surfaces which may be used to support the simulated solid fuels. 
     
     
         6 . The burner for burning gaseous fuel according to  claim 1 , wherein: the number of horizontal portions is greater than or equal to 3; the burner further comprises a combustion chamber main body connecting each of the horizontal portions together, the combustion chamber main body having a hollow structure and being provided in the middle of all the horizontal portions, wherein 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 on a bottom surface of the combustion chamber main body, the gas intake port communicates with the 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. 
     
     
         7 . The burner for burning gaseous fuel according to  claim 6 , wherein: the combustion chamber main body is provided with several combustion air inlets. 
     
     
         8 . The burner for burning gaseous fuel according to  claim 7 , wherein: upper surfaces of the combustion air inlets are higher than an upper surface of the combustion chamber main body.
