Does the LPG stove flame intensity reduces during winter?

My LPG gas stove flame is little low now a days. I have cleaned all removable parts myself, but not helped. I suspect the low temperature on winter (~18°C in winter mornings, tropical region) might affect the LPG performance, may be I'm wrong.
Anyway, I'm trying to little heats up the cylinder under sunlight.
Is it true that the LPG stove performance reduces during winter?
Best Answer
If the cylinder is outside, it could well be too cold for the liquidified gas to evaporate fast enough. Propane is OK but butane is useless this cold. A mix of the two is often sold as propane is more expensive. A mixture can become richer in butane when used for prolonged cold periods, reducing its performance.
If this is the case, lifting the cylinder indoors for a few hours before cooking should help - take it out just before use and it should stay warm enough to get things going a bit better. Don't forget that the evaporation itself causes cooling, so it can get cooler than ambient.
This is a common problem in camping, searching for camping stove performance in the cold will give you more information.

Quick Answer about "Does the LPG stove flame intensity reduces during winter?"
A lower intensity flame has nothing to do in itself with summer or winter, nor with what gas is being used (butane, methane, propane, etc.). The flame intensity is regulated by the pressure of the gas as it enters the burner.What is thermal efficiency in LPG gas stove?
The BIS- marked LPG stoves available in the market have a minimum thermal efficiency of 68% and hence, they are fuel efficient.What is the freezing point of LPG gas?
The freezing point of propane is -44 degrees Fahrenheit.What is the temperature of gas stove at low flame?
With complete combustion, an LPG (Propane) flame burns at a temperature of around 1,980\xb0C. For Natural Gas (Methane), the temperature is about 1,960\xb0C, according to the flame color temperature chart.What happens if the flame goes out on a gas stove?
Yes, leaving a gas stove on can cause carbon monoxide poisoning. All gas stoves emit carbon monoxide. That's why it's recommended to always turn on the exhaust vent when your gas stove is on.Gas Cooktop Natural Gas to LPG Conversion by ezy2learn

A lower intensity flame has nothing to do in itself with summer or winter, nor with what gas is being used (butane, methane, propane, etc.).
The flame intensity is regulated by the pressure of the gas as it enters the burner.
So the gas pressure in your lines is lower now than it used to be. If the burner is connected to a bottle or other container of gas, this is an indication that your gas bottle is running on empty and you should start looking for a replacement/refill.
If your burner is connected to the house gas grid with your central heating (for example) and that to the city network, probably the higher demand for gas due to cold weather for heating has led to lower pressure in the pipes and thus a lower intensity flame.
If that's the case, contact the company supplying your gas and ask them about it, maybe they can do something, maybe they're just running at peak capacity and can't increase pressure.
