Procedure followed to design and construct the cooking Stove
Design a prototype unit, based on interviews with Zimbabwe residents who are affected by IAP.
Test the:
- Alternative Hypothesis: A easy to construct, low-cost cooking system will significantly reduce IAP.
- Null Hypothesis: A low-cost cooking system will not significantly reduce IAP.
Key Variables
- Independent: Cooking method- Traditional hearth, Clean cooking system, Amount of fuel burned
- Dependent: Cooking particulate residue (weight), Carbon Monoxide concentration, Temperature of
stove
Experimental Procedure
- Burn constant amount of fuel using both cooking methods (Open fire vs IAP Reduction Unit)
- Measure weight of particulate residue from the smoke collected by HEPA filter
- Measure concentration of Carbon Monoxide (CO) and heat at set time intervals.
- Compare weight of fuel residue, CO concentrations and heat generated..
- An infrared temperature thermometer at the different parts of the unit with respect to time
- A simple chimney with filter paper is designed to measure the weight of carbon and particulates per
unit time.
- A CO meter is used to measure the concentrations of CO present throughout the burning process
- Determine if there a significant difference in IAP and combustion efficiency between the traditional
and IAP Reduction cooking system
