Swamp gas is the common name for the hydrogen sulfide from decaying matter. In small amounts, hydrogen sulfide is relatively harmless. However, it becomes quite dangerous when present in large amounts, especially in confined spaces.
Incomplete combustion. Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. In general for incomplete combustion: hydrocarbon + oxygen â carbon monoxide + carbon + water. The carbon is released as soot.Carbon monoxide is a poisonous gas, which is one reason why complete combustion is preferred to incomplete combustion. Gas fires and boilers must be serviced regularly to ensure they do not produce carbon monoxide.ost of the energy is released as heat, but light energy is also released. About 21 per cent of the air is oxygen. When a fuel burns in plenty of air, it receives enough oxygen for complete combustion.
