Powerpoints of panels

Workshops and Panel Discussions

Updated: April 11, 2016

The panels and workshops at the Pellet Stove Design Challenge covered a wide range of topics. Some included cutting edge research that has not yet been published so the powerpoint is not yet available to post here. A short description of the panel or workshop is followed by a link to the powerpoint, if there was one available.

Wednesday, April 6

  1. Team Presentations
    Each of the finalist teams in the 2016 Pellet Stove Design Challenge had an opportunity to do a presentation on the design and operation of their stove and how they achieved improved performance. Moderator: Rebecca Trojanowski.

    Niels Wittus & Rene Bindig, Pellwood
    Vance Hirst, Sr. & Jr, Seraph Industries
    Geoffrey Johnson, Torrefire
    Steven Spevak, VibraStove
    Joseph Mollendorf, University of Buffalo team

  2. Pellet Stove Design:
    How has pellet stove design evolved over the years, and what innovation has succeeded. Why do many heat exchangers still appear to be undersized? Most stoves on the market continue to have far too much excess oxygen. What are the trade-offs and barriers to lowering oxygen, expanding heat exchangers and other design options?
    Moderator: Ray Albrecht, consultant;

    Jock Gill, Whitfield Biochar
    Scott Williamson,

  3. Repeatability & Testing of Popular Pellet Stoves
    Panelists will discuss factors that impact repeatability and reproducibility in pellet stove testing. How does real world performance of pellet stoves compare to lab performance?

    Tom Butcher, Brookhaven Labs
    Norbert Senf, Masonry Heater Association
    Rebecca Trojanowski, Brookhaven National Lab.

  4. Air Quality and Pellet Stoves.
    This panel will look at indoor PM issues and CO from combustion and pellet off gassing. Moderator: Marc Cohen.

    Prof. Phil Hopke, Clarkson University
    Prof. Andrea Ferro, Clarkson University

  5. Thursday, April 7

  6. Policy and regulator issues.
    Panelists will address the NSPS and how its impacting pellet stoves, the new, voluntary hangtag, how BTU heat output is calculated on the list of EPA certified stoves, among other issues.
    Moderator: John Ackerly.

    Adam Baumgart-Getz, EPA;
    Rod Tinnemore, Washington Department of Ecology;
    Lisa Rector, NESCAUM

  7. Pellet Stove Testing Workshop 1
    This workshop takes place in lab 815 and involves testing with portable emission meters made by Testo and Wohler. Portable equipment can be an efficient way to prepare for certification testing.
    Leaders: Rebecca Trojanowski, Brookhaven Lab; Craig McKim, Testo;

  8. Pellet Stove Testing Workshop 2
    This workshop brings attendees into lab 526 to show how stoves are tested for EPA certification under a dilution tunnel and how filters are pulled and weighed to measure particulate matter.
    Leaders: Tom Butcher, Brookhaven Lab; Rebecca Trojanowski, Brookhaven Lab

  9. The European Pellet Stove Market.
    Emissions standards are tightening in Europe and “green labels” are pushing pellet stoves in Europe to become cleaner and more efficient. Testing protocols are also being consolidated. How will these changes impact the technology and the market for pellet stoves in Europe? How will these changes abroad impact the North American market?
    Moderator: Tom Butcher

    Jytte Boll Illerup, Technical University of Denmark
    Ricardo Luis Teles de Carvalho, SBi/Aalborg University, Denmark
    Marius Wohler, University of Applied Forest Sciences, Rottenburg, Germany

  10. Determining Pellet Stove Efficiency.
    Panelists will discuss CSA B415.1 and other efficiency issues and calculation methods, including how manufacturers advertise efficiencies to the public.
    Moderator: Norbert Senf

    Tom Butcher, Brookhaven Lab
    Gael Ulrich, Ulrich Research & Consulting
    Crispin Pemberton-Pigott;

  11. The Development of Automated Cord Wood Stoves.
    In Europe and North America, several new and existing companies are developing and marketing wood stoves with automated combustion controls. Will there be a demand for these stoves? What are the technical and regulatory hurdles? Do they function well enough yet?
    Moderator: Mark Knaebe

    Ryan Fisher Taylor Myers, MF Fire
    Jake Lindberg, Stonybrook University Ben Myren, Myren Labs

  12. Retrofit technology: from prototype to deployment.
    The Puget Sound Clean Air Agency held a retrofit technology competition for wood stoves, and after extensive testing found three prototypes that met strict PM reduction goals. Panelists will discuss the next steps toward deploying this technology and barriers that need to be overcome.
    Moderator: Dave Atkins

    Jeff Hollowell, Biomass Controls
    Lance Grace, Grace Fire
    Rod Tinnemore, Washington State Department of Ecology;

  13. Commercial Efficiency Protocol Development.
    This panel will explore an accepted testing protocol for the seasonal thermal efficiency performance of commercial sized boilers.

    Ben Bell-Walker
  14. Friday, April 8

  15. Deployment Strategies for Pellet Stoves
    Panelists will review incentive and change-out programs for pellet stoves and assess their successes and challenges. Panelists will also address the importance of eligibility criteria, workforce development, measurement and verification, and other program goals.
    Moderator: John Ackerly

    Stephen Faehner, American Wood Fibers
    John Crouch, HPBA
    Rod Tinnemore, Dept. of Ecology, Washington State.

  16. Ultra-fine particles from bark and wood.
    Panelists will review the science of health impacts of wood smoke with a focus on nano-particles, including differences between smoke from bark and wood.
    Moderator: Jonathon Kays.

    Barbara Panessa, Brookhaven Lab
    Patricia Fritz, NY Department of Health
