Sounds like wick problems. If the wick is too long, you get a smoky yellow flame and the wick gets sooted up. Sometimes, you can clean the soot off or burn it off, but it's difficult, and many people don't bother trying, but replace the wick right away.
Be careful to fill the tank without spillage, to keep every part of the stove washed off with detergent and hot water, and keep the flame low. A blue flame is a lot hotter and a more efficient way to burn kerosene.
Bad kerosene may be the problem, but this is extremely unlikely. and if that's the problem, you need to change your kerosene supply (and supplier) and your wick as well, because the impurities will have deposited themselves in the wick.
Incomplete combustion causes the yellow color in the flame. The combustion needs more oxygen in order for the flame to be blue. On a gas stove, it could be caused by dirt in the jet, or the opening that determines oxygen:gas ratio may need adjusting. Another very interesting thing is that if it just started to happen, and it happens on all burners, you might check if a humidifier is being used in the house. Believe it or not, that will turn the flame yellow. Turn off the humidifier, wait several hours, and try it again.
Lack of oxygen, or some table salt (solution)
Bunsen Burner flames turn to yellow color at 1,000 °C .This is due to incandescence of very fine soot particles that are produced in the flame.
not enough oxygen
The gas is not completely burned.
The luminescence in the cooler yellow flame is caused by closing the air vents of a Bunsen burner. This is the result of incomplete combustion.
Yellow soot is obtained when the holes of the burner are not clean. The combustion is incomplete. The yellow soot or yellow flame is because of unburnt carbon particles.
No, a yellow flame is colder than a blue flame.
The hottest flame is the blue flame and the coolest flame is yellow.
You don't have to use the yellow flame but its not recommended for heating as its a lot cooler than the blue flame.

The silent flame on the Bunsen burner is the yellow/orange flame.
yellow flame
As a safety flame, keep it on this if the burner is not in use :)

The two types of flames a Bunsen burner can produce are a luminous, yellow flame and a "roaring" blue flame. The blue flame is much hotter than the yellow flame.
The coolest flame on the Bunsen burner is the yellow-orange flame - approx. 300 0C.
The coolest flame on the Bunsen burner is the yellow-orange flame - approx. 300 0C.
The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.
The whiter the flame, the hotter.
its hotter than a yellow flame
