  • Densified Wood Fuels Rebecca Snell, Gareth Mayhead, and John R
    Woody Biomass Factsheet – WB2 Densified Wood Fuels Rebecca Snell, Gareth Mayhead, and John R. Shelly University of California Berkeley Wood has likely been valued by people as a fuel that can supply heat since the first lighting strike to a tree was observed! Wood is often the fuel of choice because it is readily available, burns easily, and is renewable. The rapid expansion of the energy needed to fuel the industrial revolution, however, emphasized the value of other fuels such as coal and crude oil that are more energy dense (higher energy value per unit volume). Densification is a process of compressing a given amount of material into a smaller volume in such a way that the material maintains its smaller volume. Densification improves the positive attributes of wood fuels while retaining the environmental benefits of a renewable fuel and improving its comparison to fossil fuels [1, 2]. These include: • Uniform size and shape promotes efficient transportation, storage, and automatic feeding systems • Consistent low moisture content • Greater energy density than non‐densified wood, reducing transportation costs • Provide a uniform, reliable source of a renewable natural resource as a fuel supply Densified wood fuels are manufactured to a particular size and shape for a given market. Typically, wood particles are compressed into pellet, log, or brick shapes. Figure 1 shows the relative amount of various fuel types needed to produce about 15,000 Btu of heat. Bricks Air dried firewood Pellets Firelog Wood chips Figure 1. Comparison of the volume of different fuel types needed to produce an equivalent amount of heat.

  • Wood-Burning Devices and Amend Rule 444 – Open Burning
    Note to Public: At its May 3, 2013 meeting, the SCAQMD Governing Board is considering all parts of Proposed Amended Rules 445 and 444, except specific provisions related to beach fire rings. Beach fire rings will be considered at the June 7th Board meeting. BOARD MEETING DATE: May 3, 2013 AGENDA NO. 29 PROPOSAL: Amend Rule 445 – Wood-Burning Devices and Amend Rule 444 – Open Burning SYNOPSIS: The 2012 Air Quality Management Plan (AQMP) was adopted by the SCAQMD Board in December 2012 and was subsequently approved by CARB in January 2013. AQMP modeling has indicated the benefits of episodic fine particle emission reductions for attaining the federal 24-hour PM2.5 standard by 2014. The proposed rule amendments are intended to implement 2012 AQMP control measures BCM-01 [Further Reductions from Residential Wood-Burning Devices] and BCM-02 [Further Reductions from Open Burning]. Proposed Amended Rule (PAR) 445 – Wood Burning Devices will lower the threshold for a wintertime wood burning curtailment, establish criteria for a basin-wide curtailment, and set standards for solid-fuel labeling for wood and wood-based products by commercial firewood sellers. Additionally, PAR 444 – Open Burning will incorporate the winter season burn restriction consistent with PAR 445. Other minor amendments to both rules are proposed to improve rule implementation clarity relative to existing requirements. Lastly, a prohibition of opening burning in beach areas will be considered at the June 7 Board Meeting. COMMITTEE: Stationary Source, March 15, 2013, Reviewed RECOMMENDED ACTIONS: Adopt the attached resolution: 1. Adopting Proposed Amended Rule 445 – Wood Burning Devices; and 2.

  • Logging in to a New Market
    Logging in to a New Market Alberta’s Buchanan Lumber has moved into utilizing residual wood in a big way, producing firelogs made from wood shavings, and selling the logs everywhere from Quebec to Texas. By Tony Kryzanowski Putting another log on the fire has taken on new meaning. Today, it could mean a firelog manufactured entirely from wood residuals—and that’s a product that Alberta’s Buchanan Lumber has considerable experience manufacturing at its High Prairie sawmill. Northern Alberta is somewhat of a hotbed when it comes to converting wood residuals to energy products, with wood pellet mills operating at LaCrete Sawmills in LaCrete and at Vanderwell Contractors in Slave Lake. Buchanan Lumber, however, has taken a different approach, opting instead for firelogs and fuel pucks. “Our firelog is really an overgrown wood pellet,” says Ken Dobson, the owner of Forestech Enterprises Ltd. Based in Edmonton, he has considerable consulting experience, dating back nearly 30 years, first with Coutts Machinery and then with Almac Machine Works. Dobson helped Buchanan Lumber research firelog manufacturing technology, worked with them to install a Swiss technology-based unit, and continues to regularly monitor the equipment’s performance. “These firelogs basically have the same BTU characteristics as wood pellets,” he adds. “The technology is out of Europe, where these types of machines and the market for these logs are very popular, and is probably 60 years old.” Buchanan Lumber has a well-established philosophy aimed at full log utilization. The sawmill produces about 110 million board feet of lumber annually in dimensions from 2” X 3” to 2” X 6” up to 10’ in length from its spruce and pine wood diet.
