Question

table salt thrown on LPG gas flame immediately yellow spark form on that place. ​

Answer 1

Answer:

A blue gas flame indicates complete combustion. Red or yellow gas flames may be the sign of incomplete combustion.

With hydrocarbon flames, such as gas, the amount of oxygen supplied with the gas determines the rate of combustion. This is the most important factor in determining the colour of the flame.

Blue Flame = Complete Combustion

Explanation:

Open Stovetop

If you want to fix the problem of a yellow flame yourself, allow the stove to cool, remove the top grates and lift up the stovetop to expose the burner piping. On most stoves, the air shutter is just behind the burner gas valve. It is a sliding plate or tube that covers the burner air vent.
