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.

∙ 6y agoIncomplete 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.
