Abstract
Woody biomass heating projects are becoming more and more numerous in Quebec and the trend is not decreasing. In this context, the skills to guarantee the quality of the biomass will become more and more important in order to limit costs and maximize the efficiency of the systems. There is a frequent mismatch between the biomass delivered and the desired characteristics for the various bioenergy processes. Forestry companies supplying woody biomass as well as bioenergy producers need to be more aware of biomass quality criteria. To assist these companies, FPInnovations researchers have been working on this issue.
Abstract
Les projets de chauffage à la biomasse ligneuse sont de plus en plus nombreux au Québec et la tendance n’est pas à la baisse. Dans ce contexte, les compétences permettant de garantir la qualité de la biomasse deviendront de plus en plus importantes afin de limiter les coûts et de maximiser l’efficacité des systèmes. Une disparité fréquente entre la biomasse livrée et les caractéristiques souhaitée pour les divers procédés de bioénergie est observée. Les entreprises forestières qui fournissent de la biomasse ligneuse ainsi que les producteurs de bioénergie se doivent de mieux connaître les critères de qualité de la biomasse. Pour venir en aide à ces entreprises, des chercheurs de FPInnovations se sont penchés sur la question.

Abstract
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.

Abstract
Several RF pressing trials were successfully conducted in the pilot plant at the Vancouver lab of FPInnovations, which aimed at thick LVL manufacturing, use of lignin-based PF resin as a binder and new plywood pressing method. A number of 3.5-in thick LVL billets were first RF-pressed for heavy-duty packaging applications with a pressing time of being shortened to about 25 min but with satisfactory bending MOE and MOR properties. Lignin PF resin (with 20wt% phenol replacement ratio) was prepared and used to make 13-ply spruce LVL. Compared to the control, there was no significant difference in both panel flatwise and edgewise bending MOE and MOR, as well as panel delamination resistance, when the lignin-based PF resin was applied. Further plywood RF heating trials with aluminum plate separation of panels demonstrated that the inclusion of the plates can help increase the thickness uniformity of plywood panels pressed with RF heating. Economic analyses were conducted to determine the benefits of RF pressing for manufacturing LVL and plywood, and RF preheating of plywood. For RF pressing of LVL preliminary calculations demonstrated that RF pressing would generate aoubt $3.0 million CAD operating profit per year. It would also have 3.3% higher internal rate of return (IRR) and 1.25 years shorter payback period. For RF pressing of plywood, preliminary calculations indicated about $1.0 million CAD increase in operating profit annually for the RF pressing option, yielding a payback period of 3.95 years for purchasing and installing the new RF equipment. For RF pre-heating of plywood, the analysis showed that an increase of $4.7 million CAD in operating profit can be achieved annually and payback period is only 0.4 year. However, some further pilot plant work is required to establish the maximum closed assembly time of pre-heated plywood panels for industrial applications. PF adhesive formulations may also need to be changed in order to prevent glue dry-out after preheating.

Abstract
The objective of this project was to help Forintek members improve MDF manufacturing processes and maintain cost competitiveness by developing improved or new methods for mat preheating and/or humidification. MDF mat heating and humidification with steam (the H & H system) has demonstrated its great ability to increase press speed and hence production capacity in Ranger Board and WestPine MDF. Higher mat temperature allows shorter press time but it tends to drive some moisture out of the mat. Moisture content can vary significantly across the thickness of the mat depending on the conditions of the H & H system and the configurations of the formers, which have a strong influence on panel properties. It was observed that board formaldehyde emissions can be significantly increased as a result of using H & H, although emission levels can be effectively controlled by increasing the use of formaldehyde scavenger, or via resin modification, or both. Achieving the balance of mat temperature and moisture content and hence obtaining the optimal H & H conditions is challenging. Trial and error has been the only approach available to the mills so far. The approach of computer modeling, however, should be an excellent enhancement to the empirical approach. Based on mill data from WestPine MDF and Ranger Board, a preliminary computer model for mat heating and humidification with steam has been developed. It can be used to develop a deeper understanding of the individual process parameters and their interactions within the H & H system, improving process efficiency and product quality as well as training mill operators. In co-operation with Hydro Quebec, an experiment on microwave preheating of MDF mat was conducted. It was observed that moisture movement within the mat upon microwave heating was from the centre of the mat to both surfaces and towards the edges and corners. The moisture variation was much higher across the thickness of the mat than among different locations of a layer of the mat. The variations are thought to be related to the mat density profiles, electric field distribution and penetration depth. During hot pressing, PressMan profiles showed higher core temperatures for the microwave-preheated mat than the control for most of the press cycle. Based on the work carried out for this project, the following conclusions and recommendations are made: 1. A preliminary computer model has been completed for the MDF mat heating and humidification system at Ranger Board. It is now ready to customize to mill conditions. 2. A preliminary computer model has been completed for the MDF mat heating and humidification system at WestPine MDF. It is now ready to customize to mill conditions. 3. Microwave preheating of MDF fibre mat increases the initial mat temperature and re-distributes and moves moisture towards the mat surfaces. 4. As a result of moisture re-distribution, the moisture gradient and temperature gradient are in the same direction at the early stage of the hot pressing. Due to this effect of positive coupling between moisture gradient and temperature gradient, heat can be transferred significantly faster from the surfaces to the core and heat flux is also increased. 5. With microwave preheating, the increase of core temperature in MDF fibre mat starts earlier and the rate of the temperature increase is greater. 6. As a result of microwave preheating, hot press cycle time may be substantially reduced, leading to increase of production efficiency.

Abstract
In 2000, the Saskatchewan Department of Highways and Transportation (SHT) conducted two trials of heavy trucks equipped with tire pressure control systems and operating on rural roads. The Forest Engineering Research Institute of Canada (FERIC) participated in an advisory capacity and prepared this summary of the trials. The main objectives involved quantifying the potential benefits of optimized tire pressures in minimizing damage to rural roads, and offsetting the incremental road damage caused by larger capacity trucks carrying enhanced weights. Tire heating and fuel consumption were also examined.
