Abstract:

The purpose of this analysis is to find out the effect of stretch on syngas premixed flame with air. The analysis is done at ambient condition of temperature 300 K and 1 atm pressure. The fuel is syngas which is also known as synthetic gas or producer gas. This is mixture of gases like hydrogen, carbon monoxide, methane, carbon dioxide and nitrogen. Out of which carbon dioxide and nitrogen act as inert while burning and heat energy is produced from hydrogen, carbon monoxide and methane. This syngas is mixed with air which acts as an oxidizer. The mixing is done before burning, therefore the flame front formed is called as premixed. The present analysis is done with very rich condition of syngas in air with equivalence ratio of 1.8 in counter-flow arrangement with increasing velocity of premixed syngas and air from both the nozzles. As the velocity increases the stretch in flame also increases. The temperature, velocity and species distribution of hydrogen, carbon monoxide and methane are analysed in current study.
