What part of the flame is the coolest?

The hottest part of the flame is at the tip of the outer blue cone (up to 1200°C). The coolest part of the flame is inside the inner blue cone, where combustion is incomplete.

What is the difference between Bunsen burner and spirit burner?

Answer:A Bunsen Burner is a device to burn a gas fuel in a single flame for the purpose of heating with a minimum of light, usually for laboratory purposes. A Spirit Lamp uses a liquid fuel in a reservoir and burning the vapor, usually with an adjustable wick. It is typically used for lighting, rather than heating.

Which is the hottest part of the gas flame?

Non-luminous zone
​ The Hottest part of the gas flame is known as the Non-luminous zone. The Non-luminous zone flame is blue. In this zone, complete combustion of the fuel takes place because there is plenty of air around it. The outermost zone has the highest temperature in the flame.

Which part of the lighter flame is hotter?

Actually, the hottest part of the candle flame is the blue part, at 2552 degrees F (1400 C.) That is where the flame has the most oxygen and you are getting complete combustion. The reddish part is the coolest part, about 1472 F (800C).

What does a cool flame indicate?

A cool flame is a flame having maximal temperature below about 400 °C (752 °F). It is usually produced in a chemical reaction of a certain fuel-air mixture. Contrary to conventional flame, the reaction is not vigorous and releases very little heat, light, and carbon dioxide.

What fuel does a spirit burner use?

The spirit burner is intended for alcohol based fuels only (such as methylated spirit). Alternative safe fuels are other alcohols based on Methanol or Ethanol e.g., Surgical Spirits or Wood Alcohol. At least 70 % alcohol will work. Ethanol will give the best effect and you get most energy from it.

What is a spirit burner used for?
