TEMPERATURE CONTROL METHOD OF NATURAL GAS IN FUEL SUPPLY LINE OF GAS-TURBINE ENGINE Russian patent published in 2015 - IPC F02C9/40 

FIELD: power industry.

SUBSTANCE: according to temperature control of natural gas for a fuel supply line of a gas-turbine engine, which involves stages at which percentage content of natural gas consisting of methane (CH₄), ethane (C₂H₆), propane (C₃H₈), butane (C₄H₁₀), carbon dioxide (CO₂) is measured by means of an infrared analysis, percentage content of nitrogen (N₂) is calculated as addition to 100% of the measured percentage content of methane (CH₄), ethane (C₂H₆), propane (C₃H₈), butane (C₄H₁₀), carbon dioxide (CO₂), an index meaning energy content of natural gas is calculated, and natural gas temperature is controlled based on the above index.

EFFECT: invention allows improving efficiency and reliability of a thermal power plant.
