Referring to fig. 1 to 7, a multi-channel combustor includes:
the burner comprises a burner base 10, wherein two outer ring gas nozzles 12 and an inner ring gas nozzle 11 are arranged on the burner base 10 in a specified sequence;
a distributor 20, the distributor 20 being disposed on the burner base 10;
the splitter 50 is arranged at the upper part of the distributor 20, and the splitter 50 is provided with splitter holes 51;
the outer ring fire cover 30 is arranged above the splitter plate 50, and the outer ring fire cover 30 is matched with the splitter plate 50 to form an outer ring gas cavity;
a central fire cover 40, the central fire cover 40 being disposed at the center of the top of the distributor 20;
the inner ring gas channel 21 is arranged on the distributor 20, one end of the inner ring gas channel 21 is an inner ring gas inlet 211, the inner ring gas inlet 211 is opposite to the inner ring gas nozzle 12, and the inner ring gas channel 21 is communicated with the central fire cover 40;
the outer ring gas nozzles 12 are arranged on the outer ring gas channels 22, one end of each outer ring gas channel 22 is an outer ring gas inlet 221, the outer ring gas inlets 221 face the outer ring gas nozzles 12, the splitter plate 50 covers the outer ring gas channels 22, the splitter holes 51 are communicated with the outer ring gas cavities and the outer ring gas channels 22, and the two outer ring gas channels 22 are symmetrically arranged on the distributor 20, so that gas can uniformly enter the outer ring gas cavities.
The distributor 20 is arranged on the burner base 10, the two outer ring gas channels 22 are arranged on the distributor 20, the two outer ring gas nozzles 12 matched with the outer ring gas channels 22 are arranged on the burner base 10, the existing gas channels are effectively replaced through the special structures of the two outer ring gas channels 22 and the two outer ring gas nozzles 12, each section of outer ring gas channel 22 is shorter than the existing gas channel, the gas inflow stroke is shorter, the situation that the pressure is insufficient to bulge the gas at a specified speed when the gas is conveyed to the tail end is prevented, the gas bubbling amount at the same time is increased, the pressure of the gas entering the outer ring gas cavity is more sufficient, and therefore, compared with the prior art, the pressure of the gas entering the outer ring fire cover 30 can be effectively ensured, and the phenomena of backfire and fire deflection can not occur, but also makes the combustion more violent.
Since most of the air required for the gas is supplied from the outside of the gas burned in the outer ring when the gas is burned in the outer ring, which may result in a situation where the air supply is insufficient when the gas is burned in the outer ring and the gas is burned in the inner ring, for this reason, it is preferable that the distributor 20 is higher than the burner base 10 by a predetermined height, the inner ring gas channel 21 and the outer ring gas channel 22 are disposed at the bottom of the distributor 20, and a vent hole is further included between the central fire cover 40 and the outer ring fire cover 30, which communicates the lower part and the upper part of the distributor 20. So that air can be introduced between the center fire cover 40 and the outer ring fire cover 30 from the space between the burner base 10 and the distributor 20 through the ventilation holes, thereby sufficiently securing the air supply inside the inner ring flames and the outer ring flames.
With the above technical solution, preferably, the inner ring gas channel 21 is disposed in the middle of the bottom of the distributor 20, the two outer ring gas channels 22 are bent along the direction of the outer ring gas cavity, the ends of the two outer ring gas channels 22 are connected, the inner ring gas channel 21 is surrounded by the two outer ring gas channels 22 in the middle, and the two outer ring gas inlets 221 are respectively located at two sides of the inner ring gas inlet 211, as shown in fig. 6, it can be ensured that the gas enters the outer ring gas cavity more uniformly, and certainly, the two outer ring gas channels 22 can also be disposed at the bottom of the distributor 20 in a circularly symmetric manner, but this would make the arrangement of the two outer ring gas nozzles 12 more inconvenient.
In order to further ensure the combustion of the gas, a negative pressure channel is formed between the outer ring gas nozzle 12 and the outer ring gas inlet 221. Therefore, when the gas is sprayed to the outer ring gas channel 22, a negative pressure is generated at the negative pressure channel, so that the air is driven to enter the outer ring gas channel 22, and then the air and the gas are premixed in the outer ring gas channel and enter the outer ring gas cavity through the diversion hole 51, so that the gas is already in a mixed state of the gas and the air when sprayed out from the outer ring fire cover 30, and the combustion is more complete.
Similarly, a negative pressure channel is formed between the inner ring gas nozzle 12 and the inner ring gas inlet 211.
As a further improvement of the above scheme, in order to enable the negative pressure channel to generate negative pressure better, the outer ring gas inlet 221 and the inner ring gas inlet 211 are flared from inside to outside.
Further improved, the inner ring of the outer ring fire cover 30 is provided with a plurality of fins, and a left-handed or right-handed fire channel 31 is formed between two adjacent fins, as shown in fig. 7.
The above is only the preferred embodiment of the present invention, not limiting the patent scope of the present invention, all of which are under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct or indirect application is included in other related technical fields in the patent protection scope of the present invention.
