HEAT TRANFSER OF STOVE FOR PERU By Scott
HEAT TRANFSER OF STOVE FOR PERU By Scott Bartz April 14, 2008
Stove Design • Firebrick combustion chamber • Three inches of vermiculite insulation • Concrete Shell • Steel top (not shown in photos) Front View Top View
The Project � Test how long it takes to bring 5 gallons of water to boil from a cold and hot start.
Testing Procedure • Use 2 kg of equally dried wood for both tests • Record starting temperatures and how long it takes each one to boil • Measure how much fuel was left out of the 2 kg • Measure how much water was left from both tests • Measure the air temperature during both tests • Use the calculations from “Design Principles for Wood Burning Cook Stoves” in order to analysis the two different tests
Heating Analysis Time (min) Temperature (degrees Celsius)
Conclusion � Cold start took a lot longer to bring to a boil than we had anticipated. � Hot start took a LOT less time to bring to a boil than the cold start test previous and used less fuel. � In order to determine our stove performs to what they currently use we will have to perform similar test with what they now use.
