During the spring and summer of 1995, FERIC observed a series of tests aimed at reclaiming log sortyard residues and processing them as hog fuel for power boilers. These tests were conducted by MacMillan Bloedel Limited in the Port Alberni area on Vancouver Island. The equipment used in the tests consisted of excavators, a portable trommel, a metal detector/rock-picking conveyor belt, a portable hog and a crawler tractor. This report presents data on material composition, productivities and costs of the different treatments, and product analyses.
FPJoule is a web-based tool that can be used to evaluate the amount of energy contained in harvest residues according to their origin (species group and part of tree) and moisture content. The tool can also be used to quantify the financial advantages when using biomass as a fuel source compared to conventional fossil fuels. A more comprehensive spreadsheet model is also available to FPInnovations members. The latter version can be modified to match a particular facility, such as boiler efficiency.

FPJoule est une application web permettant d’évaluer la quantité d’énergie fournie par des résidus forestiers selon leur origine (groupe d’essences et partie de l’arbre) et leur teneur en humidité. L’outil permet également de quantifier les avantages financiers liés à l’utilisation de la biomasse comme source d’énergie pour le remplacement des combustibles fossiles. Un modèle de feuille de calcul plus complet est également disponible pour les membres de FPInnovations. Cette version peut être modifiée pour correspondre à une installation particulière, comme l’efficacité des chaudières.

The Forest Engineering Research Institute of Canada (FERIC) and Alberta-Pacific Forest Industries Inc. examined the feasibility of recovering logging slash and converting it to power boiler fuel (hog fuel). This report presents hogging productivity and costs, hog delivery costs, hog fuel quality, and cost comparisons with natural gas.
The Forest Engineering Research Institute of Canada (FERIC), in cooperation with Tembec Industries Inc., performed two case studies in southwestern British Columbia. The first case study examined the feasibility of converting harvesting residues into chunks for producing hog fuel, and collecting and hauling roadside residues for producing pulp chips and hog fuel. The second case study evaluated the feasibility of recovering sawmilling residues for pulp chip and hog fuel production. In each study, FERIC determined system productivities and costs, and assessed the quality of the furnish produced.
