GAS-TURBINE-EXPANSION INSTALLATION FOR THE COMPRESSED ROCK GAS ENERGY UTILIZATION Russian patent published in 2006 - IPC F25B11/00 F17D1/04 

FIELD: power engineering; power generating installations.

SUBSTANCE: the invention is pertaining to the field of power engineering, in particular, to the power generating installations utilizing the energy of the overpressure of the rock gas with realization of the gas-turbine-expansion effect. The gas-turbine-expansion installation for utilization of the compressed rock gas energy contains in series mounted on the high-pressure rock gas mains: the electric heater for preheating of the gas; the turbo-expander kinematically linked with the electric power generator; the power storage battery with a capability of its recharge from the electric generator at the turbo-expander operation in the recharge mode and at connection to the heater in the initial moment of the installation operation with the subsequent switching-off from the heater at the turbo-expander reaching its operational mode. The electrical heater is the resistive heater and connected to the electric power generator through the control unit, which is electrically connected to the temperature sensing devices mounted on the inlet and the outlet of the turbo-expander. Utilization of the invention ensures simplification of the design chart of the power gas-turbine-expansion installation and the capability to regulate the preset temperatures of the gas at the inlet and the outlet of the turbo-expander.

EFFECT: the invention ensures simplification of the design chart of the power gas-turbine-expansion installation and the capability to regulate the preset temperatures of the gas at the inlet and the outlet of the turbo-expander.
