The heat energy resulting from the complete combustion of a fuel, expressed as the quantity of heat per unit weight of fuel. The high heat of combustion is the potential available, and the low heat of combustion is the high heat of combustion minus several losses that occur in an open system (primarily heat of vaporization of moisture in the fuel) .
is the heat evolved when a definite quantity of a substance is completely oxidized (burned).
The heat change which occurs when one mole of a substance is burnt in an excess of oxygen.
The heat released when a substance is completely burned in oxygen. Compare HEATING VALUE.
The Heat of combustion (ΔcH0) is the energy released as heat when a compound undergoes complete combustion with oxygen. The chemical reaction is typically a hydrocarbon reacting with oxygen to form carbon dioxide, water and heat.
