Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a biomass boiler. Background Art

[0002] In the food industry, a biomass boiler is a heating device that uses biomass energy as fuel. Specifically, this type of boiler uses agricultural and forestry waste, wood processing waste, or specialized biomass pellets as combustion materials to generate heat.

[0003] Biomass boilers use renewable biomass fuels. The amount of carbon dioxide released when these fuels are burned is roughly equal to the amount of carbon dioxide absorbed by plants during their growth, thereby achieving carbon neutrality. Therefore, biomass boilers are needed. However, due to the relatively simple design structure of traditional biomass boilers, it is not convenient to remove the filter in the smoke pipe, and it is not convenient to clean the waste. If the filter is not removable, cleaning will become very difficult, which may cause the filter to be blocked and affect the normal operation of the boiler. As the filter is blocked, the ventilation efficiency of the flue will decrease, resulting in lower boiler combustion efficiency, which may increase fuel consumption and reduce thermal efficiency. At the same time, the accumulation of waste and ash will occupy the combustion space, reduce the effective combustion area, and lead to lower combustion efficiency. Utility Model Content
