Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
The yellow flame (or luminous flame) should not be used because 1. It is less hot that the blue flame (or non-luminous flame) 2. It produces soot, as compared to the blue flame which is the clean flame
The object should be placed at the tip of the inner blue cone of the bunsen burner flame. This is the hottest part of the flame and will provide the most efficient heating to the substance. Adjust the height of the object as needed to maintain the best heating.
The very hot flame of a Bunsen burner can burn a variety of materials, including natural gas, propane, and other flammable gases. It can also be used to vaporize and burn liquids or solids, making it a versatile tool in laboratory settings for heating, sterilizing, and performing chemical reactions. Care should be taken to ensure safety when working with a Bunsen burner.
A non-luminous (blue) flame is ideal for heating solids as it provides a consistent and even heat distribution. A non-luminous flame is hotter than a luminous flame, making it more efficient for heating purposes. Additionally, it reduces the risk of leaving soot or unburned fuel residue on the solid material.

Luminous since it is visible
Leaving the Bunsen burner with a luminous flame while not in use helps prevent gas leaks by indicating that the gas is on. It also maintains a constant temperature for when it needs to be used again quickly.
This is not a very well worded question. What do you mean by why should it be used? I Bunsen burner is used for heating things, usually in a lab setting.
When heating something gently with a Bunsen burner, you should use a low flame, often referred to as a "yellow flame" or "safety flame." This flame is cooler and provides a steady, controlled heat suitable for delicate tasks. It is achieved by partially closing the air supply to create a luminous flame, which is ideal for situations where a gentle heat is required to avoid overheating or splattering.
because.
because it isnt hot enough and will leave soot on the bottom of the thing you are heating
