Forecasting the energy characteristics of a gas turbine during the transition to synthesis gas

Purpose. The paper shows the possibility of using Balakhtin coal for the production of synthesis gas by gasification followed by its use in a gas turbine. The purpose of the study was to evaluate the efficiency of the Balakhtin coal gasification process and determine the main characteristics of the generated generator gas. It is shown that coal gasification produces a generator gas with an average heat of combustion of 4608.41 kJ/Nm³. As a result of the calculation, the number of main components in the gasification products, the excess air coefficient, the proportion of water vapor introduced, and the synthesis gas output were determined. The resulting synthesis gas can be sent to a gas turbine to generate electricity. The article presents the effect of natural gas and generator gas produced during gasification of Balakhtin coal on the energy characteristics of a gas turbine. This comparison makes it possible to predict changes in the energy characteristics of the gas turbine unit (GTU). Methods. To solve the tasks set in the scientific article, a computational research method was used. The following research objects were selected: Balakhta brown coal and synthesis gas obtained during coal gasification. Results. The results of computational studies of solid fuel gasification in a flow-through gas generator are presented. A comparison of the effect of the obtained synthesis gas and natural gas on the energy characteristics of a gas turbine is presented. Conclusion. The synthesis gas produced as a result of gasification is a promising alternative fuel for gas turbines, which will reduce the consumption of natural fossil fuels and reduce the negative impact of coal on the environment.
