'Heating values' 'Heating values' (or 'calorific values') are measures of the amount of energy contained within a given quantity of fuel. Heating values are therefore expressed in terms of energy per mass or energy per volume of fuel - e.g. GJ per t, kWh per L.. Heating values allow the conversion of fuel quantities into their corresponding quantity of energy.

Lower Heating value calculation from chemcial combustion equation of Butane. up vote 1 down vote favorite. QUESTION Butene, C4H8 is burned in an engine with a fuel-rich air-fuel ratio. Dry analysis of the exhaust gives the following volume percents: $ce{CO2} = 14.95%$, $ce{O2} = 0%$, $ce{CO} = 0%$, $ce{H2} = 0%$, $ce{C4H8} = 0.75%$, with the rest being $ce{N2}$. Higher heating value .

The heat of combustion of a fuel is commonly referred to as the heating value or the caloric value and briefly defined as the amount of heat released when a unit amount of the fuel is completely combusted. The heating value is a unique characteristic of each specific fuel. The heating value of a fuel may be categorized as either the higher heating value (HHV) or the lower heating value (LHV .

Calculating the Heat of Combustion for Natural Gas

Maintaining the efficiency of a heating process depends on knowing (or calculating) the heat of combustion of a fuel. In some cases, it's sufficient to use an approximate value, such as 1,000 BTU/ft3 for natural gas.

2 DETERMINING A MORE ACCURATE HEATING VALUE OF NON-RECYCLED PLASTICS (NRP) BACKGROUND Mechanical recycling of post-use plastics into new products can conserve resources and reduce energy

chemical enthalpy of the fuel is denoted as net heating value h u (earlier designation lower heating value). Both values are thus differentiated only by the proportion of the condensation enthalpy hu H0 xH O ∆hvap 2 = − ⋅ (3-1) H2O x being the proportion of water in the gas. Table 3-1 lists the gross heating values and the net heating values for .

The quantity known as higher heating value (HHV) (or gross calorific value or gross energy or upper heating value) is determined by bringing all the products of combustion back to the original pre-combustion temperature, and in particular condensing any vapor produced.
