Smokeless and environmental protection production of sawdust briquette machine is the problem that people concern. It also accord with energy conservation and environmental protection policy of our country, so how to implement smoke-free production of the sawdust briquette machine?

The production of sawdust briquette machine has high efficiency and energy saving. It is equipped with a flue gas treatment system, which can bake the flue gas produced in the process of making charcoal and purify it and turn the flue gas into combustible gas, tar and wood vinegar liquid. The combustible gas can be recycled, wood tar and wood vinegar liquid can be collected and stored for centralized sales. All kinds of crop straw, wild grass, wood, deciduous leaves, forest waste, rice husk, corn cob, peanut husk, sawdust, twig nut shell, bark and other plants containing wood fiber can be used to make biomass charcoal after intensive processing.

Carbonization is an important part of making charcoal. It’s like building a building. The good raw material is the foundation of the building and it is the underground part. The carbonization technology in the carbonizing process is the above-ground part of the building. Carbonization is divided into three stages: low temperature moisture eliminating, high temperature calcining and cooling. The briquettes contain about 8% of water before carbonization, thus the time for moisture eliminating is essential. The moisture eliminating time is generally 10-15 hours for the earth kiln and 2-3.5 hours for the carbonizing furnace. Long heating time can prevent the briquettes from cracking, ensure the quality of carbonization. Ventilation first after finish carbonizing to prevent carbon dioxide poisoning. The charcoal out of the kiln should be left outside for more than 8 hours to prevent the resurgence of fire.

Reducing environmental pollution and avoiding the waste of forest resources are the reasons why the briquette machine industry occupies an important position in today’s society. The application of briquette machine effectively avoids the waste of forest resources. Sawdust briquette machine mainly takes straw, fruit shell, agricultural and forestry waste as raw materials, which not only avoid waste, but also make waste resources reuse. Charcoal produced by briquette machine can be used for barbecue, household heating, etc. The heat value of charcoal is higher than coal. It can also be processed into chemical raw materials for activated carbon, silicon carbide, crystalline silicon and carbon disulfide.
