Flame stabilization in combustion chamber

Flame Stabilization In Combustion Chamber. Flame stabilization is usually accomplished by causing some of the combustion products to recirculate and hence to continually ignite the fuel mixture. Flame holders cause a pocket of stagnated burning flow which helps to ignite the fuel-air mixture The combustion chamber is long enough to allow most of the combustion to happen inside such that radiated heat from the burning gas ignites the fuel-air mixture upstream. The combustion air is guided via. For this purpose a down-scaled staged can combustion system provided with an optical combustion chamber was investigated in a high pressure test rig.

Flame Stabilization Aero Notes from aeronotes.weebly.com

Flame may blow out at lean fuelair or at rich fuelair mixture. Mass flow rate of the kerosene and oxygen injected into the rocket is set to be a small value below 10 of the total fuel when the equivalence ratio of the second combustion is 1. This is taken as limit of stability in which flame will hold. FLAME STABILIZATION AND PROPAGATION IN HIGH VELOCITY GAS STREAMS By G. The goal is to limit peak flame temperatures below a value where thermal NOx production is. Flame to traverse the combustion chamber is halved in milliseconds.

Abstract The results are presented of the experimental and computational studies of the flame stabilization behind a swirler in an open flow and in a model compartment of the combustion chamber.

Flame to traverse the combustion chamber is halved in milliseconds. Flame may blow out at lean fuelair or at rich fuelair mixture. Mass flow rate of the kerosene and oxygen injected into the rocket is set to be a small value below 10 of the total fuel when the equivalence ratio of the second combustion is 1. For the development of a fuel flexible low-emission and reliable combustion system a better understanding of the flow field flame interaction and the flame stabilization mechanism is necessary. The fuel is not premixed with the combustion air so similar tradeoffs of NOx versus soot emissions occur as in CI. Stability Limit Combustion Chamber Performance.
