    A chemical reaction happens when kerosene is burnt which produces gases that come out as smoke.

    Is there no any way to reduce it(smoke)? or by changing stove burning mechanism.

    Well the smoke is due to the hydrocarbons present in the kerosene,

    It is (atleast now) impossible to expect an engine or apparatus burning or running on fossil fuels to run without smoke.

    You can try for lower smoke emissions if you are that interested by taking pure fuel and making the perfect burning of the fuel.

    when kerosene is burnt the unburnt carbons and some of the burnt gases will be emitted as soot and smoke
    to decrease these smoke and soot, all the carbon atoms are to be burned
    in the case of stove we use natural gas on burning it almost all carbons will be burnt

    Thats what I've said

    LPG you use the gas relatively pure under high pressures so giving out 100% carbon burning.

    Hi
    The smoke is produced because of the following:
    1- Presence of impurities
    2- Heavy Hydrocarbone existance in the Kerosene section used
    3- Fresh air is not enough
    4- There may be a technical problem in your stove
    Generally, the smoke is produce because of the burning process (i.e. reaction of kerosene with Oxygen O2) is not done completely.
    To improve that or to reduce the smoke, you have to check the notes above (remove the impurities, use lighter kerosene section, provide excess fresh air, and check your stove)
    My regards

    The smoke is due to the incomplete combustion of the hydrocarbons, especially the unsaturated ones which have a higher C %. The amount of air being supplied to eh burning fuel is insufficient and hence the smoke. However, please note that smokeless kerosene stoves do exist. I had used one about 40 years ago.

    The smoke is becouse of presence of carbon existing in combustion product.
    Carbon is always present in fuel in form of hydrocarbon. When we burn this fuel and air is not available in proper quantity or air-fuel mixing is not proper soot will form.
    Breakdown of unburned hydrocarbon will take place and coke will form due to tigh temp. created by combustion reaction. If this coke in not getting converted in CO or CO2 becouse of less amount of air or improper mixing, will result smoke formation.

    So you want smokeless flame try to atomize ur fuel this result in proper air fuel mixing and smikeless flame.
