Embodiment 1

[0042] see Figure 1~2. The flat layer blow-out biomass pellet burner shown in this embodiment includes a silo 1 , a feeding mechanism 2 , a burner 4 and an ignition device 8 . The discharge end of the feeding mechanism 2 communicates with the end of the burner 4 for continuous delivery of biomass particle fuel to the burner. The burner 4 is in the shape of a truncated cone installed horizontally, and the bottom surface of the truncated cone is the end of the burner 4 .

[0043] The flat layer blown-out biomass pellet burner shown in this embodiment also includes an air distribution chamber 3 connected to the end of the burner 4 and communicated with the air outlet pipe of the combustion-supporting fan 9 . Preferably, the air distribution chamber 3 is in the shape of a hollow ring, and the feeding mechanism 2 and the ignition device 8 pass through the air distribution chamber 3 from the hollow.

[0044] The air distribution chamber 3 has a combustion-supporting air pipe 7 p...

Embodiment 2

[0047] In order to facilitate the control of the firepower of the flat-bed blow-out biomass pellet burner, on the basis of Embodiment 1, this embodiment further sets a plurality of evenly distributed combustion-supporting air ducts 7 in the air distribution chamber 3, and in the combustion-supporting fan The air inlet of 9 is equipped with an electric damper 10 and a temperature sensor 5, which is inserted into the inner cavity of the burner 4 from the end of the burner 4, and the temperature sensor 5 is arranged above the slag blowing pipe 6. In this way, the combustion conditions in the burner 4 are monitored in real time through the temperature sensor 5, and parameters such as fuel feed rate and air flow are controlled individually or jointly, so that the input firepower of the burner can be freely adjusted.

Embodiment 3

[0049] This embodiment demonstrates the control method of the flat layer blow-out biomass pellet burner shown in Embodiment 1.

[0050] The biomass particles leak into the feeding mechanism 2 from the bottom of the silo 1, and the feeding mechanism 2 transports the biomass particles to the end of the burner 4 and accumulates near the ignition device 8.

[0051] The biomass particles are ignited through the work of the ignition device 8; the combustion-supporting air is sent into the air distribution chamber 3 through the combustion-supporting fan 9, and then horizontally enters the end of the burner 4 from the combustion-supporting air pipe 7, so that the biomass particles are fully Combustion: The ashes after combustion are directly blown out of the burner 4 horizontally through the slag blowing pipe 6 to ensure continuous combustion of biomass particles.

[0052] A controller 12 is installed on the frame 11 to control the feeding speed of the feeding mechanism 2 . When the ...

Abstract

The invention belongs to the technical field of new energy resources and energy saving and particularly relates to a level layer blow-out type biomass particle burner. The level layer blow-out type biomass particle burner comprises a material bin, a feeding mechanism, a burner port and an ignition device, wherein the material outlet end of the feeding mechanism communicates with the tail end of the burner port; the level layer blow-out type biomass particle burner further comprises an air distribution chamber; the air distribution chamber is connected with the tail end of the burner port and communicates with an air outlet pipe of a burning-supporting fan; and the air distribution chamber is provided with a burning-supporting air pipe pointing to an inner cavity of the burner port and a slag blowing pipe stretching into the burner port and located in the lower portion of the inner cavity of the burner port. The level layer blow-out type biomass particle burner adopts a level layer burning mode, the structure is simple, reliability is high, the maintenance workload is small, slag bonding is not liable to occur in the burning process, ash can be discharged automatically, the problemof blocking of the burner port is solved effectively, continuous feeding and continuous ash discharging can be achieved in working of the level layer blow-out type biomass particle burner, and heat supply is stable.

Description

technical field [0001] The invention belongs to the technical field of new energy and energy saving, and further belongs to the technical field of renewable clean energy, and specifically relates to a flat blowing type biomass particle burner. Background technique [0002] Biomass energy has always been an important energy source for human survival. It is second only to coal, oil and natural gas, and accounts for the fourth largest energy consumption in the world. It occupies an important position in the entire energy system. Compared with fossil fuels, biomass energy has the following salient features: Renewability, biomass can be regenerated through photosynthesis of plants, and it is a renewable energy source like wind energy and solar energy; Biomass resources are abundant, which can ensure the sustainable use of energy ; The process of biomass utilization has the characteristics of zero emission of carbon dioxide, and the CO required for the growth of biomass 2 equival...
