Brief Description Of Combustion Process Of Gas Fuel
From the perspective of chemical reaction kinetics of combustion, the combustion of gaseous fuels can be divided into two types: expanded combustion and dynamic combustion.
If the fuel and combustion supporting air are supplied separately and mixed and burned after entering the combustion furnace, the diffusion time between the fuel gas and combustion supporting air is still much longer than the chemical reaction time no matter how the mixing is intensified, so the combustion at this time belongs to diffusion combustion. Industrial combustion belongs to diffusion combustion.
If the fuel gas is mixed with all the combustion supporting air in advance, and after a period of time, the two have fully diffused and reached equilibrium, and the diffusion time is zero, then no matter how fast the chemical reaction proceeds, it is also the main medical factor that determines your whole time, so this is the power system. Because the dynamic combustion requires the combination of the fuel gas and the auxiliary air in advance, it is conventionally called premixed combustion.
The normal combustion process of all combustible mixtures has two stages: ignition and nuclear combustion, i.e. combustion can only be carried out after ignition
