Then, filtering and adsorption are performed through the activated carbon plate 6 to remove the remaining tiny particles, tar, harmful gases, and other harmful substances in the fuel gas. This deep purification process can ensure further improvement of gas quality and provide cleaner and safer energy for subsequent use. Finally, it is collected through the gas storage tank 8 and then added with a catalyst reaction, which can reduce the activation energy of gas combustion and enable the gas to be completely burned at a lower temperature, thereby improving combustion efficiency and reducing harmful emissions generated during gas combustion, such as nitrogen oxides, sulfides, etc., making emissions more environmentally friendly, which not only helps to extend the service life of equipment and improve energy utilization efficiency, but also helps to reduce environmental pollution and promote the sustainable development of biomass energy.
