Chauffage d'eau d'étangs à base de charbons de bois et son impact sur la variation de température: un cas d'étude en période froide à Lubumbashi (R.D. Congo) [ Heating water of ponds based on charcoal and its impact on temperature change: A case study in cold periods in Lubumbashi (DR Congo) ]

The purpose of this study is to raise the temperature of the pond water during cold in Lubumbashi, using different amounts of charcoal. Three ponds of 1.5 areas were used, and twenty barrels placed in two ponds. The first pond was not heated, the second and the third was heated using respectively 15 kg and 30 kg of charcoal per day. Temperatures were taken at different times and the data obtained were subjected to analysis of variance using SPSS 16.0 software. The results obtained showed that the addition of 15 kg of charcoal increases the temperature of a unit, respectively 19.2°C, 20.1°C and 21.4°C in ponds that have not received charcoals, with 15 kg and 30 kg of charcoals (p
