Question

How LPG burns in a gas stove with a blue non luminous fame?

Answer 1

Answer:

natural gas blue flame and an LPG blue flame burn in a different colour from other materials, like wood. For natural gas blue flame (Methane), the temperature is about 1,960°C.

With complete combustion, an LPG (Propane) blue flame burns at a temperature of around 1,980°C, which is 20°C higher than a natural gas blue flame.

You get a blue gas flame with a hydrocarbon gas when you have enough oxygen for complete combustion.

When you do have sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.

Not having a natural gas blue flame or an LPG blue flame, and having a yellow/red flame instead, could be indicative of an appliance problem.
