This utility model relates to the field of combustion technology and discloses a two-stage ignition fuel nozzle device, including a fuel nozzle mounting base. A flow regulating valve is located at the rear end of the fuel nozzle mounting base, and fuel nozzles are fixedly mounted on both sides inside the mounting base. This utility model uses the structural design of the fuel nozzle mounting base to connect two fuel nozzles separately. The flow regulating valve can control the fuel flow to each of the two fuel nozzles. When a low flame is needed, the fuel flow to one or both fuel nozzles is reduced; when a high flame is needed, the fuel flow is increased. After ignition by the ignition needle, a flame stabilizer plate stabilizes the flame. Air from the air intake pipe mixes thoroughly with the atomized fuel. A heat shield prevents heat loss and protects surrounding components. The operation of this series of mechanisms drives the switching between high and low flames, thus enabling the device to control two fuel nozzles separately, achieving the purpose of switching between high and low flames. It ensures complete combustion, eliminates fuel odor, and is suitable for various applications requiring heating.

The utility model discloses a kind of suitable for biomass mixed combustion's pinch secondary air direct-flow combustor, its structure includes the inner primary air passage for conveying pulverized coal, the outer primary air passage for conveying biomass fuel pinch secondary air passage, upper secondary air passage, lower secondary air passage and tertiary air passage;Outer primary air passage is annular and located at the periphery of inner primary air passage, pinch secondary air passage is arranged between inner primary air passage and outer primary air passage, upper secondary air passage is located above outer primary air passage, lower secondary air passage is located below outer primary air passage, tertiary air passage is located above upper secondary air passage.The scheme can cool channel nozzle, oxygen supplement for highly concentrated airflow, promote ignition by high-temperature flue gas entrainment, improve primary air jet stiffness and reduce airflow wall adhesion slag;Each passage cooperates with each other, ensure that fuel and air are reasonably distributed and mixed, which can reduce fuel cost and help carbon emission reduction.
