Smoke is the result of incomplete combustion and carries a variety of toxic by-products. Smoke includes three major components: particles, which are solids, vapors, which are finely suspended liquids, and gasses.
Smoke particles include unburned, partially burned, and completely burned substances. Unburned substances are just that, unburned items. They are lifted into smoke by the thermal column produced by the fire. Partially burned particles result from incomplete combustion. Completely particles are typically ash.
Smoke contains vapors. Vapors are small droplets of liquid suspended in the air. Some of the vapors are the result of us applying water to the fire. Other droplets result from products as they burn. When items burn they produce droplets that become part of smoke. Continue Reading →
