Web2.2.1 Structure of Turbulent Premixed Flames. In gas turbine combustors, like in many other practical combustion devices, turbulent flow conditions prevail. The degree to which the turbulent fluctuations affect the combustion and flame structure can be discussed on dimensional grounds, based on the relevant characteristic time and length scales.

WebMechanical flame arrestors are filled with metal or ceramic, which absorbs heat from a flashback, quenching it to a temperature below what is needed for ignition. This stops the flame. With a low enough hydrocarbon/air mixture flow rate, if a flame travels to the face of the arrestor, it can become stable at that point. WebA flame or flashback arrestor is a safety device designed to stop a flame in its tracks. It is therefore used to prevent flashback into cylinders or pipework. A flashback arrestor …
