Recovering Heat In Combined Heat And Power Plant
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.
