Pollutant emissions from aircraft in the vicinity of airports and at altitude are of great public concern due to their impact on environment and human health. The legislations aimed at limiting aircraft emissions have become more stringent over the past few decades. This has resulted in an urgent need to develop low emissions combustors in order to meet legislative requirements and reduce the impact of civil aviation on the environment. This article provides a comprehensive review of low emissions combustion technologies for modern aero gas turbines. The review considers current high Technologies Readiness Level (TRL) technologies including Rich-Burn Quick-quench Lean-burn (RQL), Double Annular Combustor (DAC), Twin Annular Premixing Swirler combustors (TAPS), Lean Direct Injection (LDI). It further reviews some of the advanced technologies at lower TRL. These include NASA multi-point LDI, Lean Premixed Prevaporised (LPP), Axially Staged Combustors (ASC) and Variable Geometry Combustors (VGC). The focus of review is placed on working principles, a review of the key technologies (includes the key technology features, methods of realising the technology, associated technology advantages and design challenges, progress in development), technology application and emissions mitigation potential. The article concludes the technology review by providing a technology evaluation matrix based on a number of combustion performance criteria including altitude relight auto-ignition flashback, combustion stability, combustion efficiency, pressure loss, size and weight, liner life and exit temperature distribution.

“…Overall, the current reviewed low emissions combustors all have satisfactory low power efficiency. RQL combustors have idle efficiencies ranging from 98.8% to 99.3% [25]. For lean-burn combustors, the high idle efficiency is achieved through local rich burn due to fuel staging.…”

The paper reports on the new pure ammonia combustion technology based on a bidirectional swirling flow formation. This technology allows for avoiding the application of such additional efforts as fuel preheating and blending, oxidizer modification, and plasma assistance normally required for ammonia combustion. Experiments showed that pure ammonia combustion in a bidirectional swirling flow is possible at both lean and rich operation modes. The lowest achieved value of the equivalence ratio is 0.503 compared to conventional and swirl combustors where it is equal to 0.8. This became possible due to the toroidal geometry of the bidirectional vortex chamber where convective fuel preheating occurs as a natural process and the flame front surface area is increased. The presented results allow consideration of bidirectional combustors for use in modern power plants where ammonia is applied as a hydrogen-containing fuel.
