power industry

A thermal power plant, abbreviated as a thermal power plant, is a factory that uses combustible materials (such as coal) as fuel to produce electricity. Its basic production process is as follows: When fuel burns, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the steam turbine to rotate, converting thermal energy into mechanical energy. Then, the steam turbine drives the generator to rotate, converting mechanical energy into electrical energy.

The prime mover is usually a steam engine or a gas turbine. In some smaller power stations, an internal combustion engine may also be used. They all generate electricity by taking advantage of the pressure drop during the process where high-temperature and high-pressure steam or gas is transformed into low-pressure air or condensate water through a turbine.

Facing increasingly severe environmental problems, such as air pollution control, many thermal power plants have put desulfurization devices into use. Among them, the absorption tower slurry circulation pump, as the core equipment, needs to withstand long-term load operation and corrosion and cavitation caused by materials. At this time, the sealing device, as the core part of the core equipment, is particularly important.
