Performance of Composite Fecal Sludge-Biofuel in Improved Cook Stoves

摘要

This study tested the performance of fecal sludge - saw dust biofuel briquettes (FssDbb) in three commonly used cook stoves in Kenyan households by the standardized Water Boiling Test (WBT). The governing briquettes physical characteristics obtained were; calorific value (25.93 MJ/Kg), ash content (26.7%), fixed carbon (51.3%), moisture content (5.49%) and volatile matter (15.9%). The fuel had good burning characteristics (fuel consumption, CO2, CO, specific fuel consumption, thermal efficiency, burning rate and time to boil) indicated by the cook stoves. Based on the findings, the product performance was identified as a suitable alternative to conventional fuel for households. A preliminary market study confirmed the viability of introducing the briquette fuel product in the Nakuru market.
