Definition Of Combustible Substances
A combustible substance is that which is capable of igniting and burning./p>
More About Combustible Substances
- This is an important property to consider when a substance is used for construction or is being stored
- It is also important in processes that produce combustible substances as a by-product
- Special precautions are usually required for substances that are easily combustible
- These measures may include installation of fire sprinklers or storage remote from possible sources of ignition
- A chemical process in which a substance reacts with oxygen to give off light and heat is called as combustion
- The substance that undergoes combustion is said to be combustible
- It is also called as a fuel
- Magnesium and charcoal are examples of combustible substances
- Different substances catch fire at different temperatures
- It is necessary for a substance to reach ignition temperature for it to burn
- Combustion is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species
- The release of heat can produce light in the form of either glowing or a flame
- In a complete combustion reaction, a compound reacts with oxygen, and the products are compounds of each element in the fuel with the oxidizing element
- The substances which have low ignition temperatures and can easily catch fire are called “inflammable substances”
- Complete combustion is almost impossible to achieve
- Combustion is not necessarily favorable to the maximum degree of oxidation, and it can be temperature-dependent
- The three necessary requirements for combustion are fuel, air and heat
- To put off fire, water is poured on a substance which brings down it’s temperature and it is brought down below its ignition temperature
- The job of a fire extinguisher is to cut off the supply of air, or to bring down the temperature of the fuel, or both
Applications of Combustion:
- Combustion processes occur in many modern technologies such as power production, heating, automotive and aircraft engines and even explosion research
- Application areas :
- Fuel injection
- Micro combustors
- Rocket engineering
- Reactor vessels in energy production
- Exhaust control
- Engineering of furnaces, burners & stoves
