Recovering Heat In CHP Plant More Than Doubles Fuel Efficiency For Potash Plant
A 1-million tonnes/year (1.1 million short tons/year) European potassium chloride (potash) mining company is using 21 Tranter Plate Heat Exchangers to recover heat at a combined heat and power (CHP) plant. The plant has seven engine sets, each of which generates more than 200 tonnes (220 short tons) of steam per hour. There are three heat exchangers installed on each set:
- The first heat exchanger recovers heat from the engine gas generators, which is used to preheat feedwater for steam.
- The second recovers heat for process use, to raise refining process fluids to 80°C (175°F).
- The third exchanger recovers heat for use in the main building and workshops.
In total, approximately 5.5 MW of low-grade heat are recovered, more than doubling CHP plant fuel efficiency, reducing costs and conserving fossil fuel reserves.
Triple Tranter Plate Heat Exchangers installed on each of seven engine sets more than double CHP plant fuel efficiency, heating feedwater, process liquid and employees.
