Expander-generator set for utilization of natural gas overpressure energy

摘要

The article deals with the problem of using secondary energy resources in the system of transportation and distribution of natural gas, and the possibility of generating electricity without burning fuel by reducing high-pressure natural gas at gas distribution stations. The analysis of the influence of the gas temperature at the entrance to the expander - generator unit, as well as the dependence of the power of the expander - generator unit on the gas temperature and the temperature of the low-potential source is presented. Optimal temperatures are obtained at which the power of the expander-generator unit is maximal for the given gas parameters.
