Angle β formed by plane is 30 °~60 °, it is preferable that angle β is 40 °.The selection of angle β in the present invention, it is each straight except can guarantee
The flame generated on flame mesh sheet body meets outside certain coherent effect, moreover it is possible to effectively avoid flame head-on collision or flue gas exceeded.
To make the flame full combustion in mesh sheet, preferably, the height of the centre distance base top surface of each mesh sheet
For 10~50mm, further, the spacing between each adjacent direct-injection network of fire sheet body is 20~80mm.The direct-injection network of fire each in this way
Auxiliary air supplement channel can be formed between sheet body and base top surface and each adjacent straight flame mesh sheet body, to promote flame
Full combustion.
Preferably, the top surface of the pedestal is in a ring, on each direct-injection network of fire sheet body is arranged in circumferentially spacedly
It states on the top surface of pedestal, the inside edge of the base top surface is vertical or extends obliquely downward and forms two at the center of pedestal
Secondary air complementary apertures, and the auxiliary air complementary apertures and base top surface, outer peripheral surface and bottom surface enclose and set to form above-mentioned mixed air cavity.
To keep the internal structure of burner relatively firm, preferably, the connecting tube is integrated with pedestal；Alternatively, institute
The end for stating connecting tube, which is inserted, to be connected on the mounting hole of pedestal, and processing is not only facilitated to assemble in this way, but also can be right as needed
The angle of each mesh sheet is adjusted.
Compared with the prior art, the advantages of the present invention are as follows: multiple independent direct-injection network of fire sheet bodies are set on pedestal, it is each straight
Mutually indepedent, non-interfering combustion flame can be formed in the mesh sheet of flame mesh sheet body, compared with traditional full slice system mesh sheet,
Firepower is more uniform, burns more abundant, also, folder formed by the center line Yu horizontal plane of connecting tube in each direct-injection network of fire sheet body
Angle α is 10 °~70 °, so that the flame in each mesh sheet generates rotates effe, further improves the uniform of burner firepower
Property, and gas can also be accelerated to flow, to improve efficiency of combustion.
