The development of gas turbine technologies requires the search for new solutions to improve the efficiency of gas turbine plants. The energy characteristics of a gas turbine depend on many external factors the temperature and pressure of the surrounding air including the composition of the fuel gas. This paper considers the effect of fuel gas temperature. Natural gas, synthesis gas, and aviation kerosene are considered as fuel for a gas turbine. For research, a gas turbine of the GE 6FA model was selected and its mathematical model was created. The results of calculations of the effect of fuel temperature on the energy and economic characteristics of a gas turbine are presented. The dependences of the main characteristics of the turbine were obtained. At the same time, the turbine power is assumed constant since during possible operation as part of a combined cycle gas turbine unit it is necessary to maintain a constant temperature of the exhaust gases after the gas turbine. The assumption was made the costs of heating the fuel were not considered.

“…This work aims to study the operating modes of a gas turbine installation, given the variability of the fuel gas properties depending on its field. [9] The study of the gas turbine allows us to estimate changes in the basic energy and economic characteristics when the engine operation is converted to a specific composition of the fuel gas and to predict changes in these characteristics [10][11].…”

The purpose of this paper is to study and analyze the gas turbine engine and the thermodynamic cycle of a gas turbine. The article describes the processes of influence of the working fluid composition on the parameters of the main energy gas turbines, depending on the composition of the fuel gas. The calculations of the thermal scheme of a gas turbine, which were made using mathematical modeling, are given. As a result of research on the operation of the GE PG1111 6FA gas turbine installation with various gas compositions, it was established that when the gas turbine is operating on different fuel gases, the engine efficiency changes. The gas turbine efficiency indicators were determined for various operating parameters and fuel composition. The impact of fuel components on the equipment operation is revealed.

“…This is imperative to maintain the integrity of the aircraft's fuel system. However, this must be balanced against the fact that aromatic compounds tend to generate increased particulate emissions (14,(17)(18)(19) , which in turn motivates study into the injection characteristics of such compounds.…”

The importance of fuel injection methods and their atomisation characteristics has been well described in literature. Also, there are a large number of studies in literature detailing the impact of bulk properties of conventional fuels on atomisation and spray characteristics. However, there is a lack of knowledge on how different alternative fuels, and specifically aromatic species, impact spray and atomisation characteristics. In this investigation, the impact of alternative fuels, selected aromatic species and their properties on spray atomisation was studied. Details of how different aromatic structures, bonds and other micro properties of aromatics species impact spray and atomisation characteristics were investigated. To achieve this objective, testing was conducted using a Rolls-Royce Tay engine fuel injector. It was found that the droplet sizes in the form of the Sauter Mean Diameter (SMD) correlate well with fuel properties including density, viscosity and surface tension, which is in line with other published literature. Moreover, it was found that there are several aromatic species (ethylbenzene, cumene and tert-butylbenzene) which display improved atomisation. This indicates that the size of the aliphatic groups attached to the benzene ring in the aromatic molecule impact on the drop size and thereby the combustion characteristics. The worst performers were polyaromatic naphthalene compounds. With the increasing push for fuels with selected aromatic species in the future, this study provides knowledge on the impact of their on the atomisation characteristics.
