Claire Soares, in, 2015 Turbojet with Afterburner and Convergent-Divergent Nozzle ( Figure 3–1a)For high-flight Mach number applications, an afterburner is often employed, which offers higher thrust from the same turbomachinery. This, also called reheat, involves burning fuel in an additional combustor downstream of the jet pipe. The greatly increased exhaust temperature provides a far higher jet velocity, and the ratios of engine thrust to weight and thrust to unit frontal area are greatly increased.To enable the jet efflux to be supersonic, and hence achieve the full benefit of the afterburner, a convergent-divergent nozzle may be employed. A nozzle downstream of an afterburner must be of variable area to avoid compressor surge problems due to the increased back pressure on the engine when the afterburner is lit. Usually, for engines utilized in this high flight Mach number regime, a convergent-divergent intake also is employed.
Afterburner definition is - a device incorporated into the tailpipe of a turbojet engine for injecting fuel into the hot exhaust gases and burning it to provide extra thrust. Afterburners is a state of-the-art recreation facility under the direct management of the Single Marine and Sailor Program. SMP works to ensure the Quality of Life.
This enables efficient diffusion of the ram air from supersonic flight Mach numbers to subsonic flow to suit the compressor ci fan. This is achieved via a series of oblique shock waves, which impose a lower total pressure loss than a normal shock wave. Hutten, in, 2016 10.2.1.2.2.1 Direct fired thermal oxidationA direct fired thermal oxidizer is sometimes referred to as an afterburner, enclosed flare, or a vapor combustor. Usually there is no heat recovery. It is used in VOC stream, where the VOC content is high enough to support combustion without additional fuel. There is no waste gas preheater.
The waste stream from the emission source exhaust is introduced directly into the combustion chamber. The oxidizer uses a specially designed burner to raise the temperature of the waste air stream to the predetermined combustion temperature. The clean, heated exhaust gas is then discharged to the atmosphere. It is possible to send the gas through an optional heat recovery system.
