Performance study and application of new coal-fired boiler flue gas …
In a coal-fired boiler, 4–8% of the fuel heat content is ultimately converted into thermal energy that is carried by the flue gas [1]. If the remaining heat can be recovered, it would significantly improve boiler thermal efficiency; as such, numerous waste heat recovery strategies have been investigated and implemented [2], [3], [4], [5].
