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, Pelletstoveservice.com

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

Thursday, April 7

5. 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

6. 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;

7. 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

8. 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

9. 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

10. 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

11. 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

12. 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

Friday, April 8

13. 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.

14. 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
