[0027] In order to convert biomass into thermal energy in the industrial and living fields for heating treatment, etc., compared with traditional energy sources such as coal and gas, biomass fuel can save more energy and reduce carbon emissions and greenhouse gas emissions, thereby reducing pollution to the environment. However, in actual use, the flue gas generated during its combustion will carry a large amount of dust and particulate matter, and direct emission will cause pollution to the environment.
