In general combustion or burning is a chemical reaction in which a fuel combines with oxygen. When there is insufficient oxygen, burns incompletely and produces by-products of combustion. Incomplete combustion by-products of carbon-based material often have a color (red nitrogen dioxide) or an odor (aldehydes). There are a lot of combustion appliances including space heaters, gas ranges and ovens, furnaces, gas water heaters, gas clothes dryers, wood or coal-burning stoves, and fireplaces. The common fuels burned in these appliances are natural or LP gas, fuel oil, kerosene, wood, or coal.
