Under global energy shortages and carbon-reduction pressures, boiler flue‑gas waste‑heat recovery has become a focal point: by installing efficient exchangers at the flue outlet, waste heat at 140 °C–180 °C can be reclaimed to preheat combustion air or generate high‑pressure steam—boosting thermal efficiency by over 10%, saving fuel costs, and cutting thousands of tonnes of CO₂ annually. Plate exchangers offer up to 90% efficiency in medium‑ to low‑pressure settings, while shell‑and‑tube units excel under high‑pressure, high‑flow, and corrosive conditions. Success hinges on selecting SO₂/SO₃‑resistant materials, providing online‑cleaning ports, conducting thermal‑balance design, and performing regular high‑pressure water or chemical cleaning to sustain utilization above 88% and extend equipment life.
