AI Technical Summary
Existing technologies for integrating volute components into turbines present significant risks of heat exchange and high costs associated with modifying the turbine structure, especially when converting conventional cycle turbines into regeneration cycle turbines.
The volute assembly is designed with opposite winding directions, and the first port of the volute is formed by spaced-apart duct sections, with the smallest cross-section of each duct located at the larger cross-section of the other duct, limiting heat exchange and reducing the impact on the turbine structure.
The overall dimensions of the volute were optimized, limiting heat exchange between fluids, reducing the impact on the turbine, facilitating volute integration, and minimizing modifications to the turbine structure.
