Influence of Emissions Normalisation Methods on H

This dataset includes the supplemental data for the research paper entitled: “Influence of Emissions Normalisation Methods on H2-CH4 Fuel Comparisons in Generic and NOx-Abated Gas Turbine Combustion”.Parametric experiments were performed using CH4-H2 blends to fuel a model gas turbine combustor at elevated inlet conditions. This was done unabated for the first dataset, and a second time whilst employing exhaust gas recirculation (EGR) as a NOx-abatement technique. The net heat input (thermal power) and pressure conditions at which data were collected are detailed in the supplemental data files.Experiments with steam injection were also carried out as part of this experimental campaign, and are included, but these did not feature in the published paper.The purpose of the experimental campaign was to quantify emissions at different conditions, and assess the performance of conventional dry, 15% O2 NOx correction (ISO) against an alternative mass by heat input (MBHI) normalisation to experimentally verify simulated work from the literature, while expanding on this work to cover NOx-abated combustion.Emissions data were captured downstream of the combustor exit using a 9-hole equal-area probe. NOx concentrations were measured via a Signal 4000VM heated vacuum chemiluminescence analyser. Separate sample gas was cooled using a chiller system to approximately 2°C after which CO, CO2, and O2 measurements were performed using a Signal 9000MGA.Modelling to determine cycle efficiencies was conducted via AspenPlus V12, and equilibrium calculations were carried out using a combination of ANSYS Chemkin and Gaseq.Please see the included readme file for guidance on the content of the different files in this repository.
