The quantity of solid waste generated in Nigeria is increasing and its composition is becoming more diversified. Conversion of combustible solid waste to energy has been proven worldwide. The mechanism to recover the waste heat depends on the temperature and other characteristics of the waste heat gases. The aim of this study was to determine experimentally, the combustion characteristics of dry solid waste. These characteristics included firing rate, moisture content, flame temperature - time variation. Samples of combustible waste were collected, dried, weighed and combusted in a fabricated incinerator, and the desired data were collected for analysis. Results obtained, revealed that the average moisture content for the waste sample collected was 13.29%, firing rate was 2.60 kg/hr, flame temperature was 621.0 oC and mean range flame temperature 178 – 621 oC. Furthermore, the various combustible waste values obtained showed that this combustible waste can be utilized for water heating, space heating, and other medium range temperature heat recovery devices. Therefore, the information provided could be used for the design of heat energy recovery devices.
