Description

Technical Field

[0001] The utility model relates to the technical field of cotton stalk biomass boilers, and specifically relates to a feeding device for a cotton stalk biomass boiler. Background Technique

[0002] A cotton stalk biomass boiler is an environment-friendly boiler that uses cotton stalks as fuel. It converts biomass energy such as cotton stalks into heat energy to provide steam or hot water for industrial production and residential life. This boiler has the characteristics of energy conservation, environmental protection, good economy, wide applicability, etc., and conforms to the concept of sustainable development. During the combustion process, the cotton stalks burn fully, and the emitted pollutants are relatively less, which helps to reduce environmental pollution. At the same time, the operating cost of the cotton stalk biomass boiler is relatively low, the fuel source is wide and renewable, and it is one of the important choices to replace traditional fossil fuel boilers.

[0003] When the existing cotton stalk biomass boiler feeds materials, because the material volume is relatively large and relatively loose, this leads to blockage during feeding. If an effective anti-blocking mechanism is not equipped, it will directly cause unstable combustion of the boiler. This instability may be manifested as phenomena such as flame pulsation, incomplete combustion, or frequent flameout. Feeding blockage will cause discontinuous fuel supply, making the boiler unable to maintain a stable combustion state, thereby reducing the thermal efficiency and operating efficiency of the boiler. This will not only increase the energy consumption and operating cost of the boiler, but also may affect the normal operation of downstream equipment and production plans. Feeding blockage may also cause a series of safety hazards, such as backfire, explosion, etc. For this reason, a feeding device for a cotton stalk biomass boiler needs to be proposed.
