Description
Biogas cooking uses methane-rich gas from anaerobic digestion to power stoves with high flame temperatures and low emissions when properly balanced.
Technical
Methane combusts in the presence of oxygen to form carbon dioxide and water vapor, releasing energy that can reach up to ~1,900 °C at the optimal air‑fuel ratio. The process is highly efficient when the biogas has a methane content above 50 % and moisture below 15 %, and when the stove is well-ventilated to avoid incomplete combustion and CO formation.
