Аннотация: The study investigates the enhancement of marine gas turbine performance through the integration of thermochemical recuperation and the steam reforming of methanol. Experimental research was conducted using a full-scale open-cycle gas turbine unit equipped with a modular recuperative system and a steam-reforming reactor. Tests demoПоказать полностьюnstrated that operating with reformate gas containing up to 64% of hydrogen increased the turbine's mechanical efficiency from 39.1% in the conventional mode to a maximum of 44.3%, depending on the regeneration rate and fuel pressure. The optimal molar ratio of water to methanol was identified as 3.0, providing a favorable balance between hydrogen yield and system stability. Emission analysis revealed a reduction in carbon dioxide emissions by approximately 37% compared to direct methanol combustion. Additionally, nitrogen oxide concentrations decreased from 185 ppm to 160 ppm. The experiments confirmed that higher pressures of up to 3 MPa improve conversion efficiency and combustion characteristics. The results highlight the significant potential of combining thermodynamic and thermochemical recuperation in maritime gas turbines to improve energy efficiency while achieving substantial reductions in greenhouse gas emissions.
