At present, the research and development of bioenergy technology has become one of the major hot topics in the world, attracting the attention of governments and scientists from all over the world. The wood pellet machine, as the main equipment for producing biomass energy pellet fuel, bears a significant responsibility. The future development prospects of biomass pellet fuel have been highly valued by the state and have been included in key scientific and technological research projects. The wide application of biomass pellet fuel is more conducive to environmental protection and air pollution control, thus opening the curtain on building a "Green China". Today, let's listen together to what the biomass pellet machine manufacturer tells about the main differences between wood pellet fuel and coal.
1.Comparison of carbon content.
The carbon content of biomass boiler fuel pellets is relatively low, with the highest carbon content being only about 50%. Compared with coal-fired boilers, their calorific value is lower.
2. Comparison of hydrogen content
The hydrogen content in biomass boiler fuel pellets is slightly higher, and their volatility is significantly greater. Most of the carbon in biomass combines with hydrogen to form low-molecular-weight hydrocarbons. When the temperature reaches a certain level, they thermally decompose and release volatile substances. Therefore, biomass fuel is easy to ignite.
3. Comparison of oxygen content.
Biomass boiler fuel pellets have a high oxygen content, which is significantly higher than that of coal, resulting in a lower calorific value of biomass fuel.
4. Density comparison.
Biomass fuel has a low density, significantly lower than that of coal. It is relatively loose in texture and easy to burn out. The amount of residual carbon in ash charcoal is less than that in coal ash.
5. Comparison of sulfur content.
Biomass fuel has a low sulfur content, mostly less than 0.12%, so boilers do not need to be equipped with desulfurization devices.
6.The CO2 released by biomass is very low, and it can be regarded as zero CO2 emission compared with coal-fired boilers. The ash residue after biomass combustion can be used to make fertilizers, and the waste can be recycled, which is difficult for fossil fuel coal to achieve.
7.The ash residue after biomass combustion can be used to make fertilizers, and the waste can be recycled, which is difficult for fossil fuel coal to achieve.
8. Biomass can be mixed with coal for combustion to enhance combustion efficiency.
9. The adoption of biomass combustion can achieve the reduction, harmless treatment and resource utilization of biomass waste.
The source of bio-wood pellet fuel is very abundant. In many places, the utilization rate of crops like rice and corn stalks is very low, and at the same time, it causes environmental pollution. At present, with the emergence of biomass pellet machine equipment, biomass pellet fuel has greatly alleviated energy and environmental problems, and better created economic benefits.
