Expert Answer:

If you observe the bottoms of cooking vessels getting blackened, it means that the air holes are blocked and fuel is getting wasted and that is mainly caused because of incomplete combustion of  fuel and limiting the supply of air results in incomplete combustion of even saturated hydrocarbons, giving a sooty flame.
