Application scenarios of heat exchangers in the power industry

1. Application in power plants

Heat exchangers in power plants are mainly used for heat recovery, including two methods: waste heat recovery and exhaust gas heat recovery. Among them, waste heat recovery mainly refers to the high-temperature flue gas generated during fuel combustion, which is recovered through a heat exchanger to recover its thermal energy and then used to continue generating electricity; Waste gas heat recovery refers to the recovery of heat energy from the exhaust gas generated by a generator set through compression, cooling, and other methods, and then using it for other purposes.

2. Application in transmission lines

A large number of transformers and capacitors are required in transmission lines, which generate a significant amount of heat and can easily lead to equipment damage. Therefore, by installing radiators or heat exchangers to cool capacitors and transformers, their normal operation can be ensured and their service life can be extended.

3. Application in heating and cooling

In the fields of heating and cooling, heat exchangers are mainly used for heating and cooling media. For example, in centralized heating, heating is achieved through the circulation of hot water, which requires the use of heat exchangers to heat water and circulate the heated water back to the heating system.

 【 Conclusion 】

Heat exchangers are widely used in the power industry, from heat recovery to equipment cooling, to medium heating and cooling, all of which require the use of heat exchangers. Therefore, understanding the basic principles of heat exchangers and their application scenarios in the power industry is essential for power professionals.
