Ammonia, Methane and Hydrogen for Gas Turbines

Ammonia has been identified as a sustainable fuel for transport and power applications. Similar to hydrogen, is a synthetic product that can be obtained either from fossil fuels, biomass or other renewable sources. the 1960’s, considerable research has taken place to develop systems capable of burning the material in gas . However, it is not until recently, that interest in ammonia has regained some momentum in the energy as it is a carbon free carrier and offers an energy density higher than compressed hydrogen. . Therefore, this examines combustion stability and emissions from gaseous ammonia blended with methane or hydrogen in gas . Experiments were carried out in a High Pressure Combustion Rig under atmospheric conditions employing bespoke generic swirl burner. OH* Chemiluminescense was used for all trials to determine reactivity of the radical. were measured and correlated to equilibrium calculations using GASEQ. Results show that efficient can be achieved with high power but at very narrow equivalence ratios using both hydrogen and methane . Moreover, low concentrations of OH radicals are observed at high hydrogen content, probably as a of the high NH2 production.
