Why there is smoke when we burn wood?

Have you ever wondered where smoke came from when we made fire? Is there any fire there is always smoke?

When we burn wood, garbage, paper and others there will be a fire coming out then will be followed by the emergence of smoke around the fire. Wood, garbage, paper and others are made from a combination of hydrocarbon, water and minerals, if the temperature rises above 149 degrees Celsius, then the hydrocarbons will begin to evaporate and float in the air. At the time of the combustion process, these components will combine with oxygen and release energy that is heat and light that look like flames of fire.

Then where did smoke come from around the fire? Smoke is a suspension of small particles in the air that comes from the incomplete combustion of a fuel. Smoke is an unexpected side effect of fire. If an object is burned and the oxygen content at the site is sufficient, the burning will not smoke. But if the combustion that occurs lack of oxygen levels then the smoke will appear as a by-product of combustion. At the time of inadequate combustion of this oxygen, thus making the components are not burned out and cause the component to continue floating up over hot air. Together with oils that also evaporate to form fine particles. These particles move randomly and often carry various components and other particles. Together they form a circling pattern known as Smoke.

That is why there is smoke from burning. So already on the know why smoke can appear? So if you want to burn and do not want any smoke to appear, then make sure when the oxygen burning is fulfilled: D
And stay away from the smoke or wear a mask when you do the burning because this smoke is also very dangerous for the respiratory system of living things.
