摘　　要：This article presents a device for the storage and gasification of cryogenic working fluid,which is named a cryogenic fuelling tank.A cryogenic fuel tank can serve both as a fuel vessel and a pressure accumulator due to the regasification process that takes place inside.Application of this tank is slowed by the lack of theoretical and experimental research on its working process.This article deals with an investigation of the working process of the energy plant based on a cryogenic fuel tank coupled with a rotor-vane expander.Developed mathematical models include evaporation and condensation processes within the tank,heat exchange between gas chambers and between the tank and environment,and changes in energy due to incoming and leaving mass.Mechanical work used to determine the efficiency of a power plant is generated by a steam expander.Research shows that it is possible to achieve specific work outputs up to 110-160 kJ/kg with relative deviation of power and specific work determination equal to 1.4% and 1.9%correspondingly.
