Performance study and application of new coal-fired …
2017-2-15 · The results show that the boiler efficiency improves by 3.2 percentage point when the exhaust temperature decreases to 39 °C. Also, the pressure drop in the heat exchanger remains below 400 Pa, which results in low extra electricity consumption. The direct-cooling treatment removes 59% of sulfur dioxide and 8.8% of nitrogen dioxide.
