Investigation of the forced-convection heat-transfer in the boiler flue-gas heat recovery units employing the real-time measured database

Extra moistures condensation and extraction from the boiler flue-gas have been proven to be an effective measure to enhance the thermal efficiency of the boiler system. Previous researches on the condensing flue-gas heat recovery unit was based on the controlled lab condition or instant site measurement which was unable to reflect the long-term real performance of the boiler system with flue-gas heat recovery units. This research employed the...
