Calorific Value of LPG – Why Does It Matter?

Calorific Value of LPG – Why Does It Matter?

Liquid Petroleum Gas or LPG is one of the most preferred forms of energy source. Households’ users, restaurant owners, streetside vendors, and canteens, everyone prefers it. You know a lot about it! But have you wondered about the calorific value and its importance?

The “Calorific Value” is a widely used terminology in the industrial engineering sector. It is a vital fuel feature, defined by the amount of heat released while the fuel undergoes combustion.

So, why is LPG calorific value crucial to understand? It is the quantity of heat generated when the unit mass of the fuel burns to its last extent. In the laymen language, calorific value is the energy content defined in LPG. It helps in the determination of the energy efficacy along with the cost-effectiveness of Liquid Petroleum Gas.

Meaning of Calorific Value

Whether you are talking about natural gas or Liquid Petroleum Gas itself, they have different calorific values. Even the food you are consuming has calorific value, aka calorie.

So, in such a scenario what does calorific value means as a whole?

The calorific value is the amount of energy found in food or fuel. It calculates by measuring the heat generated once the fuel or food unit mass undergoes combustion. For instance, the specified calorific value of LPG gas is usually 46 MJ/kg. It is vital to remember that the calorific value of LPG is always higher than that of natural gas.

Incredible Fuel Efficiency

LPG has a higher calorific value compared to natural gas. That’s why the heating efficiency is also greater. It means that the energy required to heat something needs extra fuel with the natural gas. You have to burn more natural gas to match the efficiency of LPG.

It is due to the flame temperature. In the LPG, the flame temperature is higher than the natural gas. On the other hand, LPG also produces less carbon dioxide. This makes it a way more reliable source of energy and an environmentally friendly solution.

Matchless Cost Efficiency

We know that liquid fuel is a cheaper solution when compared to LPG. But it causes more damage to the machine parts due to sulphuric acid oxidation and formation.

Unfortunately, it is a costly solution when measured in the long run. The Liquid Petroleum Gas undergoes a complete computability process. For this reason, it rarely causes any damage to the machine parts. Thus, making LPG a cost-effective option.

LPG Specialty as A Factor

It is understood by now that the calorific value of LPG helps determine the energy content of LPG. It comes in handy, especially when LPG used as cooking fuel. For such a reason, it is vital to purchase LPG from a specialty provider only. A specialty provider knows the LPG form and can help in calorific value properly.


Without proper calorific value understanding, it is not an ideal solution to purchase LPG. It plays a pivotal role in its heat management mechanism as well.
