Question

what is meant by luminous and non luminous flames​

Answer 1

Answer:

A luminous flame is a burning flame which is brightly visible. Much of its output is in the form of visible light, as well as heat or light in the non-visible wavelengths.

Non-luminous flames are the ones that burn blue. These flames have access to as much oxygen as they could possibly use, so they can burn very efficiently. All of the carbon that gets used can be turned into CO2, so there's actually no soot.

In short :

(1). Luminous flame: A luminous flame is a bright yellow flame which gives of light. (2). Non-luminous flame: A non-luminous flame does glow as bright as luminous flame. It undergoes complete oxidation, so it gets much hot (high temperature) than luminous flame.

Answer 2

Non luminous flame is the one that burns blue.These flames have access to as much oxygen as they could possibly use,so they can burn efficiently.
