Introduction *According to the EIA Winter Fuels Report: • Wood as primary heat up by 33% • 2.6 million home’s primary heat • 9.8 million home’s secondary heat **EPA expects 113,000 wood stoves to be sold in 2015 **Mandates by 2020: • 2.5 g/hr PM2.5 • 70% reduction in VOCs • 62% reduction in CO *"Short Term Energy Outlook (STEO)." Energy Information Administration - EIA - Official Energy Statistics from the U.S. Government. N.p., 8 Mar. 2016. Web. 6 Apr. 2016. **Standards of Performance for New Residential Wood Heaters, New Residential Hydronic Heaters and Forced-Air Furnaces. Rep. 50th ed. Vol. 80.

Scope of Work • Subtask 1.1 Design and Fabricate Firebox • Subtask 1.2 Propane burner system • Subtask 1.3 Airflow Design • Subtask 1.4 Completion of the Year One Lumburnator • Subtask 1.5 Participate in 2016 Design Challenge **Subtask 2.4 Onsite Testing

The Firebox Firebox Dividers: • Separate fuel charges ➡ reduction in Burn Rate (BR) • Increase residence time and turbulence Dual chamber system: • Thermally oxidizes emissions • Enables staged combustion

Intermediate Results...

Afterburner • Propane fired afterburner thermally oxidizes VOC and CO • Effective during pre-burn • Propane can be used for push-button ignition

The Airflow System • Draft Control ➡ BR control • Enables electronic process control • Induction results in dilution and cooling of flue gas - Dilution important for measurement systems - Cool gas needs means smaller chimney Venturi Draft Inducer

Setup • Scale ⇾ burn rate evaluation • Anemometer ⇾ draft/dilution ratio measurements (CV) • Draft Gauge ⇾ draft changes (PCV) • Thermocouples – location specific temperatures (PCV) PCV = process control variable CV = control variable

Future Work Subtask 2.1 Catalytic Combustion Subtusk 2.2 Control system Subtask 2.3 Ignition System **Subtask 2.4 Onsite Testing Subtask 2.5 Participate in 2017 Woodstove Design Challenge
