The principle is to use thermal energy to heat water to generate steam, and then use the steam to drive 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.

[0003] The heating components of power plant units require the use of multiple sets of pipes.

Under the action of the infrared temperature sensor 14 and the smoke sensor 17, the temperature and smoke at the pipe of the heating component can be measured in real time.

[0028] Please refer to the attached figure in the instruction manual Figure 1 , the outer wall of the first installation frame 4 is surrounded by a limit assembly. The limit assembly includes a limit vertical tube 9, which is fixed on the outer wall of the first installation frame 4.
