Biomass combustor

Abstract

The invention provides a biomass combustor which comprises a feeding device. The feeding device is supported through a support. The feeding device comprises a hopper. The bottom of the hopper is provided with a feeding pipe. The feeding device is arranged in the feeding pipe. A power mechanism of the feeding device is a feeding machine installed on the tail portion of the feeding pipe. The head ofthe feeding pipe is provided with a telescoping type combustion head. The telescoping type combustion head is covered with multiple ventilating nets. Multiple ignition device sleeve pipes are arranged beside a feeding opening of the telescoping type combustion head. Wind supply branch pipes of multiple wind supply pipes are arranged below the ignition device sleeve pipes. The wind supply branch pipes communicate with the ignition device sleeve pipes. The wind supply pipes communicate with the feeding pipe. A rotating shaft of the telescoping type combustion head is connected with the power device. According to the device, under the circumstance of ensuring that the telescoping type combustion head can come into and out of a furnace opening freely, the size of the combustion area of the telescoping type combustion head can be changed, combustion fullness of biomass fuel is improved, and the flames are enhanced. In addition, the device can ensure that the flames are upward and high in heat efficiency.

Description

technical field [0001] The invention belongs to the field of biomass burning devices, in particular to a biomass burning machine. Background technique [0002] At present, biomass fuel is an environmentally friendly fuel, which produces less dust, less smoke, and high combustion value during the combustion process. It has been widely used in industrial production processes, and biomass burners are widely used in tea drying. In the field of roasting, the size of the combustion head of the existing biomass burner is fixed and when the biomass fuel is burning, the direction of the flame is not vertically upward. As a dual-purpose biomass burner described in Chinese patent document CN 207486837 U, the size of the combustion pool, that is, the combustion head, is fixed. In addition, when the wind from the blower enters the combustion head, the direction of the wind will blow forward. The direction of the flame cannot guarantee complete upward combustion; the ignition device in t...

Problems solved by technology

As a dual-purpose biomass burner described in Chinese patent document CN 207486837 U, the size of the combustion pool, that is, the combustion head, is fixed. In addition, when the wind from the blower enters the combustion head, the direction of the wind will blow forward. The direction of the flame does not guarantee complete upward combustion; the ignition device in this document is one, and there is no air passage, which makes it difficult to ignite the biomass fuel at the initial ignition

[0003] In actual production, the size and structure of the combustion head is set for the furnace mouth of the tea oven. Due to the certain size of the furnace mouth, the size and structure of the combustion head of the existing biomass burner is fixed. One of the biggest disadvantages of this structure is : The combustion area is small, the firepower is small, and the biomass fuel is not fully burned, which cannot meet the needs of the existing tea oven; secondly, when the combustion head of the existing biomass burner is in use, the flame will burn forward under the action of the blower , rather than burning upwards, but it has been proved in practice that the flames burning upwards are the best

[0004] Therefore, a biomass combustion device with higher combustion efficiency and firepower requirements is very promising in the market, but there is no such device at present.
