Difference Between LPG and Natural Gas

Once refined, LPG is stored as a liquid under pressure in gas bottles or tanks. LPG processing involves the separation and collection of the gas from its petroleum base. About 60% is produced from the natural gas stream that comes out of the wellhead. The other 40%

Fuels

If the initial and final temperatures of the water is measured, the energy released can be calculated using the equation. H = δT mC p . where H = heat energy absorbed (in J), δT = change in temperature (in C), m = mass of water (in g), and C p = specific heat capacity (4.18 J/gC for water).

Calorific Value

The net calorific value, or lower heating value (LHV), does account for the latent heat of vaporization and hence is the parameter most commonly used for gas turbine performance calculations. Strictly LHV is quoted as the heat released under pressure in a constant volume when the combustion products are cooled to the initial temperature of 25C.

How to Calculate Gas Consumption in a Gas Burner

Jul 17, 2017Gas burners consume fuel based on their BTU output. Natural and propane gas have specific levels of energy contained within them. One cubic-foot of natural gas contains 1075 BTUs of energy. However, gas burners are not 100-percent efficient.
