Currently, common natural gas, coal, and oil resources are non-renewable and will eventually run out. However, there's no need to worry. Biomass energy, which we already utilize extensively, refers to various common plant materials like straw, rice husks, peanut shells, and wood. These are all renewable. As long as there's sunlight, air, and water, these raw materials can be continuously produced. The most mature form of biomass energy utilization is biomass fuel. Currently, biomass solid fuel primarily comes from biomass pellets processed by a biomass pellet machine. Biomass solid fuel has the following outstanding characteristics:
1. Biomass solid fuel is highly volatile, burns completely, and saves energy.
Biomass fuel is a high-volatility, low-carbonization, and oxygen-rich material. The average volatile content is as high as 75%-85%, which is very conducive to fuel combustion. It burns completely in biomass stoves, resulting in high utilization rates and reduced energy waste.
2. Biomass fuel is a renewable energy source.
Biomass fuel utilizes common agricultural and forestry wastes and is produced continuously annually, a feature not available with natural gas and coal.
3. Biomass fuel is easy to store and transport.
Biomass solid fuel is produced by pelletizing and briquetting low-density raw materials into high-density compressed fuel, making it easy to transport and store.
Biomass pelletizing fuel utilizes common agricultural and forestry wastes and is produced continuously annually, a feature not available with natural gas and coal. 4. Biomass fuel has a high calorific value.
The calorific value of biomass fuel generally reaches 4,000 to 5,000 kcal, comparable to that of ordinary coal.
5. Biomass fuel produces few harmful gases after combustion.
Biomass fuel is a low-sulfur product, and its combustion produces very low levels of harmful gases such as carbon dioxide, nitrogen dioxide, and sulfur dioxide, meeting national emission standards.
Based on the above points, it can be seen that wood pellets are the main energy source to replace coal in the future.
