Recovering Heat In Combined Heat And Power Plant

Potash plant with Tranter plate heat exchanger recovery technology — 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.

Challenge

At a combined heat and power plant, on seven engine sets, each of which generates more than 200 tonnes (220 short tons) of steam per hour, find three heat exchangers for each set to:

Recover heat from the engine gas generators for preheating boiler feedwater for steam generation.
Recover heat for process use, to raise refining process fluids to 80°C (175°F).
Recover heat for use in the main building and workshops.

Solution

21 Tranter SUPERCHANGER® Plate And Frame Heat Exchangers to recover heat

Results

Thanks to the exchangers’ thermal efficiency and close approach, approximately 5.5 MW of low-grade heat are recovered, more than doubling CHP plant fuel efficiency, reducing costs and conserving fossil fuel reserves.
