Team Vision for System Level Demo with Customer

During this phase, the customer joined us for a burn trial. The system performed exceptionally well, due to the feedstock chosen and ideal weather conditions. The ideal water temperature was surpassed, thus proving the capability of the system for water pasteurization. Results of the tests are discussed below, as well as recommendations for moving forward.

The final results from the test are summarized below:

Parameter Values
Starting water temperature 15 °C 59 °F
Increase +27 °C + 48.6 °F
Ending water temperature 42 °C 107.6 °F
Amount of water heated 14.22 gallons
Time elapsed 38 minutes
Date completed 4/9/17
Location Rochester, NY
Ambient temperature 11.11 °C 52 °F

Using the last 4 trials, which all had similar testing setups (excluding ambient temperatures), the data was cleaned to remove erroneous points. Linear fits were added to the data to relate the increase in temperature over time. As can be seen in the graph below, the capability of the system varies between 0.18 to 1.6 °C/minute depending on the feedstock and rate of adding material:
