In the previous article, we discussed the significance of plate heat exchangers in waste heat recovery. This article will take you to see the practical application of plate heat exchangers in working conditions and the secondary use of waste heat in power plants and printing and dyeing plants. 
How much "energy" the plate heat exchanger can exert.

A power plant in Beijing built a heating and heating station using the waste heat of the power plant’s condensate water. 
There are 8 plate heat exchangers installed in the station, each with a total heat transfer area of 40 square meters; the heating station has a heating building area of 260,000 square meters. 
The longest distance of the heating pipeline is about 1000m. The primary heat source of the plate heat exchanger is the condensate water of the power plant, the flow rate is about 800t/h, the water supply temperature is 90-95?, and the return water temperature is 70-75?; 
The circulating hot water flow of heating and heating is about 800-900t/h, the circulating water temperature is 80?, the return water temperature is 60-65?, and the recovery rate of condensate waste heat can reach 22%. This working condition has been in normal operation for 10 years. 
Significant energy saving benefits, direct cost savings of tens of millions.

A printing and dyeing factory uses a plate heat exchanger to recover the waste heat in the dyeing wastewater. The hot water in the hot water tank is supplied to the dyeing tank, and the dyed wastewater is directly discharged into the wastewater tank. At this time, the temperature of the wastewater in the tank is about 80°C. 
The waste water is pressurized by the waste water pump to send the waste water to the plate heat exchanger for cooling, release the heat and then discharge it. 
The cold water in the cooling water tank is pressurized and sent to the plate heat exchanger by a water pump to cool the dyed wastewater, absorb heat and increase the temperature from 20°C to 70°C, and then pour it into the hot water tank and supply hot water from the boiler 
Mixing, as the supply water for dyeing drainage in the dyeing tank, the waste heat recovery device has extremely significant energy-saving benefits.

RPT has been deeply involved in plate heat exchanger equipment in various industries for 13 years. It applies Alfa Laval and GEA original selection software, and has a full set of Alfa Laval and Gea versions. It can propose different solutions for various working conditions to meet 
The requirements of various working conditions do their part for waste heat recovery.
