Stoichiometric or Theoretical Combustion is the ideal combustion process where fuel is burned completely. A complete combustion is a process burning all the carbon (C) to (CO 2), all the hydrogen (H) to (H 2 O) and all the sulphur (S) to (SO 2).

By convention, the (higher) heat of combustion is defined to be the heat released for the complete combustion of a compound in its standard state to form stable products in their standard states: hydrogen is converted to water (in its liquid state), carbon is converted to carbon dioxide gas, and nitrogen is converted to nitrogen gas.
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon. They are most famous for being the primary constituent of fossil fuels, namely natural gas, petroleum, and coal.
When they burn completely: the carbon. oxidises. to carbon dioxide. the hydrogen oxidises to water (remember that water, H 2 O, is an oxide of hydrogen) In general, for complete combustion:...
Ideally, the theoretical complete combustion takes place at a mass ratio of 14.7/1. This ratio is also called stoichiometric ratio. In other words, 14.7 kg of air is needed to burn 1 kg of fuel. If defined by volume, approximately 9,500 L of air is needed to completely burn 1 L of gasoline.
1 sie 2024 · This review examines hydrogen combustion as a fuel by exploring and comparing production techniques, enriching ammonia with hydrogen as a CO 2-free option, and hydrogen applications in engines. Additionally, a techno-economic environmental risk analysis is discussed.
Key learning points. Combustion is the chemical combination of a substance with oxygen, involving the production of heat and light. Complete combustion of fuels (like hydrocarbons) involve the production of carbon dioxide and water. The chemical test for oxygen is a combustion reaction, involving relighting a glowing splint.
