Biomass particles vs coal which one is better for fuel

Biomass Particles Vs Coal Which One Is Better For Fuel

Jun 22, 2020 Biomass pellet fuel has low density, loose texture and is easy to burn out. The density of coal is higher than that of biomass pellet fuel, which results in less residual heat of biomass pellet fuel than that of coal-fired carbon. Therefore, biomass pellet fuel burns more fully and has a higher utilization rate. 2.
