Biomass sampling and analysis play decisive roles in determining the characteristics and value of the woody biomass fuel used in bioenergy systems in Canada. Sampling and analysis standards help harmonize the procedures that are used to monitor biomass quality. Because there are no Canada- wide biomass sampling standards, facilities that produce and use woody biomass have developed and implemented in-house sampling procedures of varying degrees of complexity. Given that the use of woody biomass in Canada is predicted to increase, the ability to ensure the quality of biomass will become increasingly important in order to control costs and maximize system efficiency.

Abstract
L’échantillonnage et l’analyse de la biomasse jouent un rôle décisif dans la détermination des caractéristiques et de la valeur des combustibles de biomasse ligneuse utilisés dans les systèmes de bioénergie au Canada. Les normes d’échantillonnage et d’analyse contribuent à harmoniser les méthodes utilisées pour évaluer la qualité de la biomasse. Il n’existe pas de normes d’échantillonnage pancanadiennes; les usines qui produisent ou utilisent la biomasse ligneuse ont donc élaboré et appliqué des méthodes d’échantillonnage maison de niveau de complexité variable. Comme on prévoit une augmentation de l’utilisation de la biomasse ligneuse au Canada, les compétences permettant de garantir sa qualité deviendront de plus en plus importantes pour limiter les coûts et maximiser l’efficacité des systèmes.

Utilizing forest harvest residue is an issue of growing urgency in the British Columbia forest industry, In B.C., forest residues at roadside have traditionally been burned to mitigate fire hazard or, occasionally, they have been left to rot. With an increasing demand for energy and concern over climate change and air quality, burning may no longer be the most desirable practice for dealing with residues. Further, there is an increasing demand for harvest residues by both primary and secondary users to fuel the growing bioeconomy in B.C.
This is the fourth Info Note in a series describing technical and economic aspects of small and medium scale combined heat and power systems which use biomass as fuel. The Info Note’s focus is on medium-scale organic Rankine cycle (ORC) CHP systems which produce one to two mW of electricity and 5,000 to 10,000 kW of heat. ORC technology is explained, commercially available ORC systems are described, biomass supply chain considerations are discussed, and the basic economics of an installation are reviewed.

A series of info notes was developed to describe technical and economic aspects of commercially available small-scale combined heat and power (CHP) biomass systems utilized in community and small industrial applications. The first Info note is a primer in which general information about these systems is presented. The second info note presents technical and economic aspects of small-scale gasification and internal combustion CHP units under 165 kWel. The third info note presents the design and economics of biomass supply chains for small-scale CHP systems under 165 kWel.
