Biomass burner for flue-cured tobaccos

Abstract

The invention discloses a biomass burner for flue-cured tobaccos. The biomass burner for flue-cured tobaccos comprises a ventilation chamber, a feeding device and a burning hearth, wherein the feedingdevice is installed on the head part of the ventilation chamber, and the burning hearth is installed at the tail part of the ventilation chamber. The feeding device comprises a fixed material box, afeeding channel and a feeding power motor. A comprehensive fixed plate is arranged in the ventilation chamber. A poker sleeve is welded to the top of the fixed plate. A poker is placed into the pokersleeve. The front side of a poker fixing plate is welded to the head part of the poker. The tail part of the poker extends into the burning hearth. A poking spiral transmission rod is welded to the middle of the reverse side of the poker fixing plate. A heating rod is arranged in the middle of the bottom of the fixed plate. An ignition spiral transmission rod is hinged to the head part of the heating rod. The tail part of the ignition spiral transmission rod is connected with a power output shaft of an ignition telescopic power motor. The tail part of the heating rod extends into the burning hearth. The burning hearth comprises a hearth outer wall and a hearth base. The biomass burner for flue-cured tobaccos has the advantages of being easy and convenient to operate, sufficient in burning,low in cost, free of pollution and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a biomass burner for flue-cured tobacco which uses agricultural waste to produce biomass fuel and burns the biomass fuel to extract heat energy. Background technique [0002] With the rapid development of science and technology and the continuous improvement of living standards, people's awareness of environmental protection is not gradually strengthened. Biomass energy is a world-recognized clean and renewable energy. Biomass energy fuel has the characteristics of small size, high specific gravity, resistance to combustion, and is easy to store and transport. Its volatile content of combustible base is as high as 60%-75%, and its calorific value can reach 3200-4500 kcal, full combustion, effective and precise control of combustion process and temperature. Biomass fuel, as a new type of fuel, has been widely used in heating, hot water and industrial drying and other...

Problems solved by technology

[0004] Chinese patent (Notice No. CN109185866A) discloses a biomass burner for flue-cured tobacco, including a furnace, a material conveying part for the furnace to transport biomass fuel, and an air duct for providing oxygen to the furnace. The side of the furnace is provided with a flame outlet and a material inlet. The bottom is the ash storage bin, and there is a furnace grate between the furnace and the ash storage bin. The ash storage bin is connected with the air duct to provide oxygen for the furnace from bottom to top. There is a gap between the material inlet and the material delivery part. There is a material blast port in the interval part, and the biomass fuel is blown into the furnace by the wind blown out of the material blast port; this device sets the material blast port inside the partition part, which will cause the material to be blocked between the blast port and the material conveying part , and the material is blown into the furnace cavity through the material blast port, which will cause a large amount of material to accumulate in a specific position in the furnace cavity, which will affect the combustion of the material and cause insufficient combustion of the material

[0005] Although there are relevant technical solutions for biomass burners, these biomass burners still have defects such as easy deformation of the structure and a sharp increase in failure rate at high temperatures.
