Biomass briquettes are an environmentally friendly energy product machined from biomass briquette machine. It takes renewable biomass materials as raw material, and forms solid fuel with certain specifications through mechanical compression.(What are the best raw materials for biomass briquettes?) Because of its environmental protection and sustainable characteristics, this fuel has gradually attracted widespread attention. This paper will briefly analyze the characteristics of biomass briquettes from three aspects: physical characteristics, combustion characteristics and cost characteristics.

The first is physical characteristics. Biomass briquettes are usually machined into regular shapes, such as cylindrical or square blocks, with high density, high hardness and small volume. This feature makes it easy to transport and store, and compared with traditional loose biomass products, the space utilization rate is significantly improved. In addition, due to high temperature and high pressure treatment, the moisture content of biomass briquettes are low, generally below 10%, which is helpful to improve combustion efficiency and reduce smoke and dust emission.

Followed by combustion characteristics. Biomass briquettes, as a solid fuel, have good combustion performance, and the calorific value is generally between 16-20MJ/kg, which is close to that of some coal. When burning, the amount of carbon dioxide released by biomass briquettes is low, and at the same time, because the raw material comes from plants, the released carbon dioxide can be reabsorbed by plants to realize carbon cycle, so it is considered as a low-carbon energy source. In addition, the ash produced by biomass briquettes combustion is less, and the ash is rich in minerals, which can be used as fertilizer to return to the soil and realize the recycling of resources.

The last is cost characteristics. Compared with traditional fossil energy, biomass briquettes have lower production cost and a wide range of raw materials, including crop straws, sawdust, fruit shells and other wastes. These raw materials are low in price and stable in supply, which makes biomass briquettes have economic advantages. At the same time, due to the environmental protection characteristics, the use of biomass briquettes can reduce the cost of environmental treatment, meet the increasingly stringent environmental protection policy requirements, and have higher economic benefits in the long run.

To sum up, biomass briquettes machined by biomass briquette machine have become one of the important choices to replace traditional energy sources because of the superior physical characteristics, good combustion performance and obvious economic advantages. Under the background of global energy transformation, biomass briquettes have a broad development prospect and will play an important role in promoting sustainable development.(Carbonizing furnace promotes the added value of biomass briquette)
