Smoke is the result of incomplete combustion. Smoke is the leftovers from the combustion process that did not vaporize into a gas and then burn completely. Gas stoves put off no smoke because it is very close to complete combustion of a clean burning gas.

When wood burns, oxygen is combined chemically with the hydrocarbons of the wood. The products of combustion include CO, CO2 and H2O which are all colorless, tasteless gases. However, if all the carbon of the wood's hydrocarbons is not completely combined with oxygen, smoke and soot may be released in the escaping hot gases. Also, when the steam condenses it is visible. Burning a gallon of gasoline (a hydrocarbon) produces about a gallon of water! Non-combustibles (minerals) usually remain in the ash. When other materials such as metallic magnesium burn the products of combustion are visible as smoke.
