1. **Hot water recovery:
The high-temperature cooling water discharged from the generator set is passed through a heat exchanger to exchange heat with the cooling water, transferring some of the heat energy to the cooling water, and then the hot water is used for heating, industrial purposes, or other heating needs.

2. **Vapour recovery:
The heat energy in the high-temperature exhaust gases emitted from the generator set is used to heat water to produce steam, which is then used for industrial processes, heating systems, etc.

3. **Hot air recovery:
The high-temperature exhaust gases emitted from the generator sets are exchanged with air through heat exchangers to produce hot air, which is then used for industrial drying and heating systems, etc.

4. **Genset cooling recovery:
