Case: Thermal power planet Closed circulation cooling system

This is a thermal power plant located in Philippines. The power plant currently has three 55MW gensets. Plate heat exchangers are going to help the auxiliary coolers to cool down steam generator, turbo-generator, air compressors and other BoP equipments.

A part of this project is closed circulation cooling water plate heat exchanger, it use a primary water source (circulating sea water) to cool the power plant's closed-cycle cooling water (demineralized water), which is used to cool and take away a large amount of heat generated by the operation of equipment in the power plant's production process; it can also be cooled continuously due to its own friction heat-generating equipment can also cool equipment that generates heat due to energy conversion, thereby ensuring the safe operation of the power plant.
