Combustion instability remains a critical issue limiting the development of low-emission,
lean-premixed (LPM) gas turbine combustion systems. The present work provides a …

Hydrogen is one of the most promising fuels for achieving zero carbon emissions in civil
aviation. However, the rapid flame speed would easily lead to flashback issues, and its ultra …

The recent development of the Alstom's sequential combustion system for the GT24 (60Hz)
and GT26 (50Hz) upgrades 2011 is a perfect example of evolutionary design optimizations …

This paper provides detailed comparisons of chemical reaction mechanisms of H2
applicable at high preheat temperatures and pressures relevant to gas turbine and …

This book tells the story of the power generation gas turbine from the perspective of one of
the leading companies in the field over a period of nearly 100 years, written by an engineer …

In this work, the effect of using baffles and vortex generators on the cooling performance of a
gas turbine combustion chamber is numerically investigated. The RNG k-ɛ model is utilized …

This paper presents a novel sequential combustor experiment for the study of reheat flame
responses to high-frequency, transversal thermoacoustic oscillations. The reheat …

Sequential combustion system of GT24 and GT26 engines from Alstom consists of a primary
combustor, followed by a turbine and a re-heat combustor. This technology is capable of …

It is well established that hydrogen has become one of the most promising fuels for
achieving zero-carbon emissions. However, hydrogen combustion still faces many …

Alstoms GT24 and GT26 engines feature a unique sequential combustion system [1, 2]. This
system consists of a premixed combustor (called EV), which is followed by a high pressure …
