Why should a Bunsen burner flame be blue?
Combustion is incomplete and less energy is transferred. A blue flame from a Bunsen burner transfers more energy than a yellow Bunsen flame as complete combustion gives a blue flame. This is because a yellow flame produces a lot of soot. Carbon monoxide, soot and water vapour are produced as well as carbon dioxide.
Which gas produces a blue flame?
Carbon monoxide burns with blue flame. In the presence of oxygen including atmospheric concentrations carbon monoxide burns with a blue flame producing carbon dioxide. When nitrogen gas burns, It has no color, odor or taste, and produces water when it burns in air.
What is a blue flame used for?
A blue gas flame colour means complete combustion. This indicates that the gas is being burned efficiently without any unburned and wasted gas. 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.
Does a blue flame mean carbon monoxide?
complete combustion
A blue flame from your furnace or gas stove indicates complete combustion of the gas. Besides wasted gas, higher energy bills, and more soot, the main danger of improper combustion is the increased amount of carbon monoxide (CO) produced by the combustion process.
What is hotter lava or blue fire?
While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava.
What does it mean when a natural gas flame is blue?
A blue natural gas flame colour is indicative of proper combustion and minimal wasted gas. A natural gas flame should be blue. Not having a natural gas blue flame color or an LPG (propane) blue flame color, and having yellow or red flames instead, could be indicative of an appliance problem.
When do you use a blue flame heater?
Blue flame heaters should be used almost exclusively in well-insulated indoor, and medium-sized areas as they would be inefficient if the air around them is too much for their heating capacity.
What’s the difference between a yellow flame and a blue flame?
On the flame color temperature chart, red flames or yellow gas flames only burn at around 1,000°C. As it relates to hydrocarbon gases, blue flame is indicative of complete combustion whilst a yellow flame indicates incomplete combustion.
When to worry about the color of a flame?
The only time when you should worry about the color of your flame is when it’s not orange, yellow or blue. These three colors indicate a natural burning process, with the fire either completely or partially burning all the fuel’s carbon compounds.
