What are the 3 types of flames?

There are three types of flames natural flame, carburizing flame and oxidizing flame. Natural flame has synchronized mixture of fuel and oxygen, carburizing flame has more fuel and oxidizing flame has more oxygen.

What do different color flames mean?

Flame colour meaning can be indicative of temperature, type of fuel or the completeness of combustion. For example, a blue flame is the hottest followed by a yellow flame, then orange and red flames. Hydrocarbon gases burn blue whilst wood, coal or candles burn yellow, orange or red. Accordingly, what's the hottest flame color? white-blue When all flame colors combine, the color is white-blue which is the hottest. Most fires are the result of a chemical reaction between a fuel and oxygen called combustion.

Which is the coldest part of candle flame?

The Innermost zone of a flame is dark or black:It consist of hot,unburnt vapours of the combustible material.It is the least hot part of the flame.It is the coldest part of the flame. Which zone of a candle flame gives us the light? Luminous zone consists of a partial combustion with liberation of heat in large amount and thus light is emitted.

One may also ask are candles energy efficient?

The candle was burning 2 thousandths of a gram each second which gives us a power of about 80 watts. The reason it isn't as bright as an 80W light bulb is because it's really inefficient. Most of the stuff coming off candles is heat. Only about 0.05% of the energy - so not very much at all - comes out as light. How much energy is in a candle flame? It gives the typical mass rate of burning as about 105 mg/minute for a candle having diameter equal to 21 mm, and the net heat of combustion of the paraffin fuel as around 43 kJ/gm; this yields an estimate of 4515 J/min, or about 75 J/sec (75 watts) for a typical candle.

And another question, how do you measure the energy of a candle?
