Anti-slagging biomass burner and application method thereof

Abstract

The invention belongs to the field of a biomass burner, in particular to an anti-slagging biomass burner and an application method thereof. The anti-slagging biomass burner comprises a bunker, a feeder, a primary air inlet, a fire grate, a hearth, a secondary air inlet and a fire outlet, wherein the bunker feeds materials to the hearth through the feeder; the fire grate is arranged in the hearth and is positioned at the lower part of the hearth; the primary air inlet communicates with the hearth and is positioned under the fire grate; the secondary air inlet is formed in a hearth wall and is positioned in the upper part of the hearth; the fire outlet is formed in the hearth wall and is positioned in the upper part of the hearth. The anti-slagging biomass burner further comprises a secondary air nozzle, and the secondary air nozzle comprises a vent pipe. The vent pipe is mounted on the hearth wall and is arranged along the height direction of the hearth, one end of the vent pipe communicates with the secondary air inlet, and a closed head is arranged on the other end of the vent pipe. Meanwhile, a plurality of air-out holes are uniformly distributed on the vent pipe. The anti-slagging biomass burner can effectively promote combustion, reduces the slagging amount at the outlet, and the service life of the biomass burner is effectively ensured.

Description

technical field [0001] The invention belongs to the field of biomass burners, and in particular relates to an anti-slagging biomass burner and a use method thereof. Background technique [0002] At present, there are many researches on biomass burners in foreign countries, but the woody pellet burners are the main ones, and the types are single. However, my country is a large agricultural country, and there are more straw-based biomass energy. The biomass energy currently on the market Burners generally have the disadvantage of serious slagging at the fire outlet. [0003] In view of the problems existing in the above-mentioned prior art, in the prior art, the introduction of secondary air is adopted to promote solid-phase combustion and reduce the problem of slagging at the fire outlet. However, due to the problem of the air volume and uneven distribution of the secondary air, The efficiency of solid phase secondary combustion is not high. Contents of the invention [00...

[0002] At present, there are many researches on biomass burners in foreign countries, but the woody pellet burners are the main ones, and the types are single. However, my country is a large agricultural country, and there are more straw-based biomass energy. The biomass energy currently on the market Burners generally have the disadvantage of serious slagging at the fire outlet

[0003] In view of the problems existing in the above-mentioned prior art, in the prior art, secondary air is introduced to promote solid-phase combustion and reduce the problem of slagging at the fire outlet. However, due to the air volume of the secondary air and the uneven distribution of the secondary air, the The efficiency of solid phase secondary combustion is not high
