The amount of oxygen supplied with the gas is the most important factor in determining the colour of the flame.
The air to gas ratio for natural gas is around The air to gas ratio for LPG gases is higher. The air to gas ratio for propane gas is approximately The air to gas ratio for butane gas is approximately To achieve this difference, LPG is typically provided in a smaller quantity but at a higher pressure, drawing more oxygen with it into the combustion process, giving LPG a higher air to gas ratio than for natural gas.
A yellow or red flames on gas stove is dangerous, as it is indicative of incomplete combustion and carbon monoxide CO generation. A gas cooker yellow flame is a dangerous safety problem, if it occurs with an indoor appliance like a gas stove. You could also be wasting gas.
A blue flame means complete combustion is taking place. A key warning sign that you require gas appliance servicing are yellow or red flames or a gas flame colour with a yellow burning tip.
The exceptions to this are gas fireplaces and gas log fires that are designed to have a yellow or red flames. Burners blocked with dirt can result in improper combustion, leading to soot build up inside the appliance. Flames in a gas oven should burn with a blue flame colour, meaning complete combustion, as with other gas appliances.
Blue flame in gas oven applies to the flame color of propane or natural gas cooktops, as well. The LPG propane is a blue flame because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
The exception is a gas fireplace having yellow or red flames, for a more realistic look. Burning wood has yellow-red flames due to incandescence of very fine soot particles that are produced in the flame. All gas appliances, domestic and industrial, produce water vapour, Carbon Dioxide and heat, and usually very small amounts of Carbon Monoxide. If installed and maintained correctly, the operation of the gas appliance provides quick and efficient heating, cooking, hot water and more, and the products of combustion do not create any hazardous situations.
If an appliance is not correctly installed and maintained or has been modified, the products of combustion might change, and become hazardous to the people around the appliance. Something as simple as a ventilation change getting fresh air to the appliance to sustain complete combustion may cause a gas appliance to malfunction, and create a hazardous situation for the people around. Sooty smoke, yellow or red flames or poor performance are indicators, but sometimes no indicators are obvious.
If Carbon Monoxide CO is produced and escapes the appliance into the surrounding air, it will not be obvious no smell and no taste but will be very dangerous. It is essential that gas appliances are correctly installed and serviced every two years, to maintain good combustion and safe, efficient operation.
If you experience any signs of carbon monoxide poisoning while operating your indoor gas appliance, you should stop using it until it is serviced by your gas fitter.
With complete combustion you get the maximum heat output from your gas and use less gas to generate heat with whatever appliance you are using. Keep an eye on your gas appliances and have them serviced, as needed, to keep them operating properly and safely.

The miners sell the sulfur for about Indonesian rupiah per kilo less than 25 U. They can carry loads of to pounds 80 to kilos once a day—or twice if they work into the night.
When Grunewald photographs Kawah Ijen, he wears a gas mask as protection against toxic gases, including sulfur dioxide. Pallister described the miners' daily routine as "tough duty. Some of the miners do have gas masks that visitors have given them, said Grunewald, but they "have no money and no opportunity to change the filters. When she and her colleagues work in Indonesia, "we usually bring gas masks and leave them there with the people we work with, because sometimes they don't know that what they are breathing is harmful.
Grunewald has also documented the blue glow on the Dallol volcano in the Danakil Depression, in the Afar region of Ethiopia near the borders of Eritrea and Djibouti. The heat of magma sometimes ignites the sulfur dust in the soil, forming flames of electric blue. The depression is geologically active, with hydrothermal vents and sulfur springs, some of which are tourist attractions. All rights reserved. The glow is actually the light from the combustion of sulfuric gases, Grunewald explained.
