[0002] The gas turbine is an internal combustion power machine which uses continuous flow gas as working medium to drive impeller to rotate at high speed and convert the energy of fuel into useful work. In order to ensure the stable operation of the gas turbine, the gas turbine is usually installed in a steel structure plant to meet the requirements of heavy equipment and modular layout.
