As an expert in the field of combustion and fuels, I can provide you with a detailed explanation of the temperature of an LPG (Liquefied Petroleum Gas) flame. LPG is a versatile fuel that is commonly used for heating, cooking, and as a fuel for vehicles. It is primarily composed of propane and butane, which are hydrocarbons that can combust in the presence of oxygen to release energy.
The adiabatic flame temperature is a theoretical temperature that a flame would reach if no heat were lost to the surroundings. This is an important concept when discussing the temperature of a flame because it provides an upper limit on how hot a flame can get under ideal conditions. For propane and butane, which are the main components of LPG, the adiabatic flame temperatures are indeed close to 1970 degrees Celsius when burned in air. However, it is important to note that this is a theoretical maximum and actual flame temperatures can be significantly lower due to heat loss to the environment, incomplete combustion, and other factors.
In practical applications, the temperature of an LPG flame can vary widely depending on a number of factors, including:
1. The composition of the LPG: The specific blend of propane and butane can affect the flame temperature. Propane has a higher adiabatic flame temperature than butane.
2. The air-to-fuel ratio: The stoichiometric ratio for complete combustion of propane in air is approximately 1:5 (by volume), and for butane, it is about 1:12.5. If the air-to-fuel ratio is not optimal, it can lead to incomplete combustion and a lower flame temperature.
3. The design of the burner: The efficiency of the burner can greatly affect the flame temperature. A well-designed burner can ensure a more complete combustion and a higher flame temperature.
4. Environmental conditions: Factors such as ambient temperature, humidity, and wind can all influence the flame temperature.
5. The presence of impurities: Impurities in the LPG can affect the combustion process and the resulting flame temperature.
It is mentioned that 300-400 degrees Celsius is reachable, which is a more realistic figure for the actual flame temperature under typical conditions. This temperature is still quite high and is sufficient for many applications, including cooking and heating. However, it is significantly lower than the theoretical adiabatic flame temperature due to the reasons mentioned above.
Safety is paramount when dealing with LPG and other flammable gases. Proper ventilation, adherence to safety guidelines, and the use of appropriate equipment are essential to prevent accidents and ensure the safe use of LPG.
In conclusion, while the adiabatic flame temperature of LPG's main components, propane and butane, is near 1970 degrees Celsius, the actual flame temperature in practical applications is often much lower, typically in the range of 300-400 degrees Celsius. Understanding the factors that influence flame temperature is crucial for the safe and efficient use of LPG.

LPG is mostly propane and butane both of which have adiabatic flame temperature near 1970 degrees C when burned in air. See Flame Temperatures of some Common Gases. So 300-400 degrees C is certainly reachable.Feb 19, 2015
