The wood chip dryer is an important part of the biomass fuel production equipment. By drying the wood chips, it can be further granulated to produce wood pellets for combustion. Next I will mainly explain the characteristics of wood chips and the industrial application of wood chips.

  Sawdust characteristics:

  1. Renewability

  Sawdust is a renewable resource. Wood chips can be regenerated by photosynthesis of plants. They are equivalent to renewable energy sources such as wind energy and solar energy. They are rich in resources and can guarantee the continuous supply of energy;

  2. Low pollution

  There are fewer pollutants generated during the burning of wood chips; when wood chips are used as fuel, since the carbon dioxide required for the growth of wood is equivalent to the amount of carbon dioxide emitted by it, the net carbon dioxide emission to the atmosphere is approximately zero, which can effectively reduce the greenhouse effect;

  3. Wide distribution

  In areas where coal is scarce, wood chips can be fully utilized as an energy fuel;

  4. The total amount of wood chip fuel is very rich

  Wood chips are abundant in the world, and the earth's land produces between 1,000 and 125 billion tons of wood chips per year. The annual production of wood chip energy far exceeds the total energy demand in the world, which is equivalent to 10 times the current total energy consumption in the world. With the development of agroforestry, especially the promotion of charcoal forests, there will be more and more wood chips resources.

  The significance of developing wood chip energy utilization:

  With the rapid economic development and population growth, the 21st century will face the dual pressures of economic growth and environmental protection. Therefore, changing energy production and consumption patterns and developing renewable energy resources that use biomass such as wood chips and sawdust are of great significance for building a sustainable energy system and promoting economic development and environmental protection.
