Hello, fellow researchers. I need help to understand the quality of biomass (bark - eucalyptus and pine), for burning in a BFB boiler, may main concern is about the size of particles in the biomass (large particles).

I need to know the standards for burning this kind of biomass in the boiler, concerning the handling fo this materials by screw conveyors. (Too large particles may cause breaks and failures in the system).

If someone have the CEN standards to share with me I will be forever grateful.

Thank you, fellows.
