Mulciber Stove Testing Summary

Testing Overview Six Sampling Periods o Warm-Startup – 5 min. after loading for 15 min. o Warm-Steady State – 50 min. after loading for 30 min. o Hot-Startup – 5 min. after loading for 15 min. o Hot-Steady State – 50 min. after loading for 30 min. o Wet-Startup – 5 min. after loading for 15 min. o No Dilution Tunnel Particulates o Wet-Steady State – 50 min. after loading for 30 min. o No Dilution Tunnel Particulates o No Testo Data

Testing Methods TESTO g/m 3 g/hr (Estimated) PPM (CO) Efficiency (Estimated) DILUTION TUNNEL g/hr PPM (CO) ◦In the Dilution Tunnel, not the Stack

Caveats 1.None of these are official test methods; we aren’t claiming an EPA test 2.No tests were run constantly, we only have snapshots of data 3.Our burn rate was approximately 3.3 kg/hr 4.Our fan pulls in fresh air to cool itself 1.Air is diluted by 1/3 (Approximately 15% Oxygen instead of a more typical 10% in all tests) 2.This impacts PPM and g/m 3 3.This does not change grams per hour

Particulates (g/m 3 and g/hr) NOTE: TESTO AND DILUTION TUNNEL APPEAR TO BE COMPARABLE DURING STEADY STATE, BUT NOT DURING START UP. THEORY: THE TESTO DOES NOT CAPTURE UNBURNED HYDROCARBONS. IF THIS IS THE CASE, UNBURNED HYDROCARBONS MAKE UP A SUBSTANTIAL PORTION OF PARTICULATES DURING START UP.

Carbon Monoxide (PPM)

Efficiency Thermal efficiency estimated based upon heat released and heat lost E=1- (Heat Exhausted/Heat Produced)
