WebAir contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.). This process is known as oxidation.

"WebSince the ignition point of coal is around 300°C, there should be another ignition source to start the firing. This takes place in two stages: 1. The first stage is to use an igniter that provide an electric spark for supplying initial ignition energy to ignite small gas or LDO burners. This is like starting the fire in domestic gas burners. 2. " - First stage of fire also known as ignition
