Co-Combustion Characteristics of Typical Biomass and Coal

Co-combustion is considered the state-of-the-art technology to utilize biomass for replacing fossil fuels, such as coal, to meet the stationary energy demand. Several reasons account for mixing biomass with coal before burning. The co-combustion of coal and biomass blends would directly help to cut down the consumption of fossil fuels.

During co-combustion, the thermal decomposition behaviour of the blends followed that of the weighted average of the individual samples in the blends. In kinetic analysis, thermal decomposition of biomass and coal appeared to take place independently, and thus, the activation energy of the blends can be calculated from that of the two components.

Comparative Analysis of Coal and Biomass for Sustainable Energy

Biomass-derived fuel, as a renewable energy source, is often compared to coal in terms of its calorific value, which refers to the amount of heat energy released during combustion (Adeleke et al., 2024).

Overview and some issues related to co-firing biomass and coal

Direct co-firing is the most common option for biomass and coal co-firing currently, mostly due to relatively low investment needed to turn existing coal power plants into co-firing plants.
