Water-Heat-Medium technology
The water-heat-medium technology mainly functions to further recover the heat in low temperature flue gas while make sure that no corrosion is caused at the equipment so as to maximize the energy saving and minimize the energy consumption.
 
Work Principle/Flow
* The water-heat-medium system mainly consists of flue gas heat exchanger, medium heat exchanger (air preheater, feedwater preheater or other medium preheater), hot water circulation pump, regulating valve set and etc. The flue gas heat exchanger is located at the flue duct at the tail of heating furnace or boiler and the medium heat exchanger is located at the flow path of the medium to be heated.
 
* The water-heat-medium system uses a medium pressure deaerated water (2.5~5.0MPa) to maintain the operating pressure of the system and improve the saturation temperature of the heat medium water, which is helpful to improve the heat transfer grade and maximize the waste heat recovery process. During normal operation, water-heat-medium system itself does not consume any deaerated water.
 
* The hot water circulation pump functions to overcome the flow resistance of water-heat-medium system and continuously transfer the heat absorbed by the heat medium water in the flue gas heat exchanger to the medium to be heated. The bypass regulator valve is to regulate the inlet temperature of heat medium water at the flue gas heat exchanger inlet and make sure it is above the flue gas dew point temperature.
