In kerosene lamp yellow flame is produced due to partial combustion of kerosene. Partial combustion is due to lack of oxygen for burning.
But in wick - stove kerosene burns with blue flame. Because in kerosene wick stove a perforated cylinder is placed around the burning wicks.  Through these holes air is supplied continuously hence the kerosene oil vapour burns completely and produces blue flame.
