Technical Field

[0001] The utility model relates to the technical field of installation devices, in particular to an installation structure of a thermal control instrument of a thermal power plant. Background Art

[0002] A thermal power plant is a factory that uses combustible materials as fuel to produce electricity. It mainly converts the chemical energy of the fuel into thermal energy by heating water to generate steam when the fuel is burned. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The steam turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. The workshop of a thermal power plant will be equipped with thermal control instruments to monitor the thermal control system of the thermal power plant.
