Utilizing CFD Technology in the Design of the Combustion Chamber for the Hydrogen-Powered Hybrid Energy System

Addressing issues related to the enhancement of existing thermal engines and combustion processes in their combustion chambers (CC), as well as deepening our understanding of potential challenges in the improvement of gas turbine installations, opens new horizons in modern energy. Hybrid gas-steam power systems utilizing hydrogen gases and pure hydrogen offer a wide range of possibilities and potential technical solutions related to decarbonization. The paper presents the results of using Computational Fluid Dynamics (CFD) technology in the design of the combustion chamber of a hybrid gas-steam power plant with a modular construction that combines two gas turbine engines: a) utilizing the heat of exhaust gases, and b) contact type with steam injection into the combustion chamber. The main characteristics of the gas turbine combustion chamber were determined when implementing steam injection and operating the installation on pure hydrogen. Parameters of the tubular-ring combustion chamber were studied, as well as the influence of separate steam injection into different zones of the chamber to ensure its stable operation without the occurrence of flame blowout zones. Using modern computer design technologies, the impact of the distribution of environmental and energy steam on the ecological performance of a prospective hybrid gas-steam power plant has been investigated.
