Analysis of the difference between biomass fuel and coal

1. Comparison of carbon content. Biomass boiler fuel particles have less carbon content, and the highest carbon content is only about 50%, which has a lower heating value than coal-fired boilers.
2. Comparison of hydrogen content. Biomass boiler fuel particles have slightly more hydrogen content and significantly more volatility. Most of the carbon in biomass combines with hydrogen to form low-molecular-weight hydrocarbons. After a certain temperature, it is thermally decomposed to precipitate volatiles. Easy to ignite.
3. Comparison of oxygen content. Biomass boiler fuel particles contain more oxygen, and its oxygen content is significantly more than coal, which makes the biomass fuel low in calorific value.

4. Density comparison. Biomass fuel has a small density, is significantly lower than coal, has a loose texture and is easy to burn out. The amount of carbon remaining in ash is less than that in coal ash.
5. Comparison of sulphur-containing tritium. Biomass fuel has low sulfur pier, most of which are less than 0.12%. Areas with strict environmental protection requirements also need to install biomass boiler desulfurization equipment.
6. The CO2 released by biomass is very low, compared with coal-fired boilers, it can be regarded as zero CO2 emissions.
7. Ash and slag after biomass burning can make fertilizer, waste can be recycled, and fossil fuel coal is difficult to do.
8. Biomass can be combusted with coal to improve combustion efficiency.
9. The use of biomass combustion can realize the reduction, harmlessness and resource utilization of biomass waste.
