[0002] Electricity is an energy source that uses electrical energy as a driving force. Thermal power generation is the main method of producing electrical energy in my country. When generating electricity, by utilizing the heat energy generated by the combustion of combustibles in the boiler, there are three types of energy conversion processes in thermal power generation: fuel chemical energy-steam thermal energy-mechanical energy-electrical energy. Simply put, it uses the heat of fuel to heat water to form high-temperature and high-pressure superheated steam, and then the steam enters the steam turbine along the pipeline and continues to expand and do work, impacting the turbine rotor to rotate at high speed, driving the generator rotor (electromagnetic field) to rotate, and the stator coil cuts the magnetic lines of force to generate electrical energy, and then uses the step-up transformer to increase the voltage to the system voltage, connect to the system grid, and transmit electrical energy to the outside.

[0003] After a boiler has been used for a long time, it will be contaminated and dirt will form on the inner wall of the boiler, so it is necessary to clean the boiler regularly.
