A method for power generation within a gas network, and gas pressure relief means for use in the method

The invention relates to a method for power generation within a gas network with buried gas pipelines taking advantage of a gas expansion from a first higher gas pressure level to a second lower gas pressure level using at least one expansion machine, and using at least one driven by the turbomachine generator, wherein the method is carried out without gas preheating and an expansion takes place with a pressure drop Dp across the expansion machine, in which a critical dew point for a gas temperature T The method may comprise the series connection of several, preferably provide constructed as a tubular turbine flow machines within the gas system.
