Abstract

Utilization of the excess pressure energy of natural gas in the system of series-connected turbo expanders is promising from the point of view of energy saving in the gas transportation system. Theoretical work on the optimization of the regime and geometric parameters of such systems in the early stages of design is absent. In this paper, parametric studies were carried out on the effect of the project's initial data on the energy efficiency of a system of two turbo-generators with a power of up to 50 kW. Rational ranges of thermodynamic and regime ratios were found, which allows to significantly increase the design efficiency of the system of axial small-sized turbo-generators in comparison with the case of its design without taking into account the obtained information.
