Hyopthesis and Testing Method

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 sto

Experimental Procedure

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
