Because luminous flames don’t burn as efficiently as non-luminous ones, they don’t produce as much energy. This means that the non-luminous flames have a lot more energy than luminous ones, and their flames are actually hotter. This is why the luminous ones look yellow and the non-luminous ones look blue.

Which is hotter luminous or non luminous flame?
