Briefly, referring to fig. 1 and 2, when biomass gas is used for individual energy supply, biomass gas is generated by an external biomass gas generating device, then the biomass gas is output through the inner lining pipe 10, the biomass gas coming out of the inner lining pipe 10 is pushed through the multi-stage air distribution structure, in the process, the biomass gas is ignited by a high-energy arc spark generated by the high-energy igniter 30, and then the flame of the biomass gas combustion is released from the conical burner 20. When separately powered with natural gas, a pre-ignition purge is performed as programmed in the natural gas ignition protocol, the natural gas nozzle 41 then releases natural gas which is pushed through the multi-stage air distribution structure, ignited by the high energy arc spark generated by the high energy igniter 30, and the flame of the natural gas combustion is released from the cone burner 20. When the biomass gas and the natural gas are mixed for energy supply, the biomass gas is ignited by the high-energy igniter 30, the natural gas is introduced, and then the natural gas is ignited by flame generated by combustion of the biomass gas.
Therefore, the biomass gas and natural gas combustion technology is combined to form an integrated dual-purpose burner, the burner is arranged on thermal equipment (a boiler, a kiln and the like), two kinds of energy can be used alternately and independently, natural gas is used when the natural gas is sufficient, and biomass fuel is used when the biomass fuel is sufficient; the two energy sources can be used in a mixed mode, a burner does not need to be replaced, the environment is protected, the economy is realized, and meanwhile, the continuity and the stability of industrial production are guaranteed.
In some specific embodiments, referring to fig. 1 and 2, in order to make the combustion of the two energy sources more sufficient, the multi-stage air distribution structure includes a primary air outlet 51, a secondary air outlet 52 and a tertiary air outlet 61 which are sequentially arranged on the output path of the biomass fuel gas. Wherein, an annular first air chamber 50 is arranged outside the lining pipe 10, and the primary air outlet 51 and the secondary air outlet 52 are arranged on the first air chamber 50; the primary air outlet 51 is arranged on the side wall of the first air chamber 50, so that primary air is introduced into a gap between the first air chamber 50 and the lining pipe 10; the direction of the secondary air outlet 52 corresponds to the direction of the conical burner 20, and the secondary air outlet 52 is positioned closer to the conical burner 20 than the end of the lining pipe 10. An annular second air chamber 60 is arranged outside the conical burner 20, the second air chamber 60 is provided with the tertiary air outlet 61, and the tertiary air outlet 61 is arranged outside the outlet of the conical burner 20.
Specifically, taking biomass gas as an example, the biomass gas and the primary air released from the primary air outlet 51 perform primary premixed combustion, at this time, "rich fuel" combustion is performed, and the excess air coefficient a is far smaller than 1; then, the secondary air and the secondary air released by the secondary air outlet 52 are subjected to secondary mixed combustion, at the moment, fuel-rich combustion is carried out, and the excess air coefficient a is smaller than 1; then, carrying out third mixed combustion with tertiary air released by the tertiary air outlet 61, wherein the third mixed combustion is equal oxygen combustion, and the excess air coefficient a is close to or equal to 1; the whole process can ensure that the combustion is more sufficient, the combustion efficiency is high, and besides, the thermal type nitrogen oxide which is also called as the temperature type nitrogen oxide and is generated by local high temperature in the combustion process can be avoided, so that the high-efficiency low-nitrogen combustion is really realized. The combustion principle of natural gas is basically the same as that of biomass gas, but the heat value of natural gas is different from that of biomass gas, and the natural gas can be combusted by adjusting the air distribution quantity, the air distribution rate and the like.
It should be noted that the first air chamber 50 can only adopt one fan to release the primary air and the secondary air, and the air volume ratio of the primary air and the secondary air can be adjusted by adjusting the sizes of the primary air outlet 51 and the secondary air outlet 52; meanwhile, the primary air outlets 51 are holes formed in the side wall of the first air chamber 50, and preferably, the primary air outlets 51 are equidistantly arranged along the circumferential direction of the output path of the biomass fuel gas, so that the primary air can uniformly enter the gap between the first air chamber 50 and the inner lining pipe 10.

Specifically, the high-energy igniter 30 is used to generate a high-energy arc spark to ignite the natural gas ignition nozzle 71, so that the natural gas ignition nozzle generates an open flame, and when the flame detector assembly 72 detects the open flame, the natural gas starts to be introduced or the natural gas is introduced with a delay. When the biomass gas and the natural gas are mixed for energy supply, the biomass gas is ignited by the high-energy igniter 30, and then the natural gas starts to be introduced or is introduced with a delay after the flame detector assembly 72 detects an open flame. When the natural gas is ensured to be introduced, open fire exists in the combustor, and deflagration of the natural gas is avoided.
It should be noted that the natural gas ignition nozzle 71 is introduced with fuel gas or fuel oil, and then ignited by the high-energy arc spark generated by the high-energy igniter 30, so that the natural gas ignition nozzle 71 can maintain an open flame for a period of time. The flame detector assembly 72 may be a device for detecting a flame, or may be a part of a device for detecting a flame, such as a probe on a flame detector, i.e., the entire device need not be disposed in the burner, but only the probe may be disposed in the burner.

The tertiary air outlet 61 is provided with a tertiary air swirl sheet, so that tertiary air is spirally supplied along the output path of the biomass fuel gas. The primary air, the secondary air and the tertiary air are mixed with biomass gas or natural gas in a spiral flowing mode, so that combustion-supporting air is better mixed with combustible gas, and the combustion efficiency is improved.
In some embodiments, referring to fig. 1 and 2, the natural gas nozzle 41 is disposed in the outlet air path of the overfire air outlet 52, and the flame detector assembly 72 is disposed within the overfire air outlet 52. The position of the flame detector assembly 72 needs to correspond to the position of the natural gas ignition nozzle 71 to detect the open flame produced by the natural gas ignition nozzle 71. This allows the overfire air to cool the natural gas nozzle 41 and prevent the flame detector assembly 72 from being placed directly in the flame for combustion.
In some embodiments, referring to fig. 1 and 4, for further combustion, a plurality of annular air ducts 62 extend into the conical burner 20 from the second plenum 60, and the annular air ducts 62 are radially arranged along the output path of the biomass fuel gas and circumferentially arranged along the output path of the biomass fuel gas. More preferably, the air is spirally blown by the annular air duct 62.
