Description

Technical Field

[0001] The utility model relates to the technical field of biomass burners, and more specifically, to a combustion device of an external biomass burner. Background Technique

[0002] A biomass burner, as the name implies, is a combustion device that uses biomass as fuel. Biomass refers to various organic substances, including crop straws, forestry waste, and residues from wood processing. It is a device that uses these organic substances as fuel and converts them into heat energy through combustion to provide power or heat for production and life.

[0003] The working principle of a biomass burner is similar to that of a traditional fuel oil or gas burner, which is to generate heat energy through the combustion of fuel. The difference is that the biomass burner burns biomass fuel, and the combustion process of biomass fuel is very different from that of traditional fuels.

[0004] A biomass burner mainly consists of a feeding system, a combustion system, a control system, and a wind and smoke system. The feeding system is responsible for transporting biomass fuel into the combustion chamber. The combustion system burns the fuel to generate high-temperature heat energy. The control system is used to control various parameters of the combustion process, such as the opening degree of the air damper and the feeding speed, to ensure the stability and efficiency of the combustion process. The wind and smoke system is responsible for discharging the waste gas generated by combustion and ensuring the negative pressure in the combustion chamber to prevent waste gas leakage.

[0005] Currently, for the combustion cylinder on a biomass burner, due to the overly long cylinder body and the fire-intolerant material, it is prone to being burned out during long-term use. Based on the above problems, we provide a combustion device for an external biomass burner.

[0006] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the utility model. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Content of the Utility Model

[0007] In order to solve the problems raised in the above background technique, the utility model provides a combustion device for an external biomass burner.

[0008] The combustion device for an external biomass burner provided by the utility model adopts the following technical solution:

[0009] A combustion device for an external biomass burner includes a cylinder body; a push plate bracket fixedly assembled inside the cylinder body; a push plate disposed at the bottom of the push plate bracket; and the cylinder body is twenty-five centimeters long.

[0010] Place the biomass fuel under the push plate, then ignite the biomass fuel for combustion. By setting the cylinder to be 25 cm long, the cylinder can be prevented from being burned out.

[0011] Preferably, the push plate bracket fixedly assembles the push plate through a vertical rod.

[0012] Preferably, a plurality of through holes are formed at the top of the push plate bracket.

[0013] Preferably, a refractory layer is fixedly connected to the inner wall of the cylinder.

[0014] Preferably, a connecting plate is fixedly connected to the side end of the cylinder, and a plurality of through holes are formed on the side surface of the connecting plate.

[0015] In summary, the present utility model includes the following beneficial technical effects:

[0016] By placing the biomass fuel under the push plate and then igniting the biomass fuel for combustion, by setting the cylinder to be 25 cm long, the cylinder can be prevented from being burned out. By providing a refractory layer, the fire resistance of the cylinder can be increased, and the service life of the cylinder can be extended. By providing a connecting plate, the installation of the cylinder is facilitated. Through this structural design, the combustion of the biomass fuel can be ensured, and at the same time, the fire resistance of the cylinder can be increased.
