Presents the structure principle, engineering application, selection of design parameters for heat recovery steam generator (HRSG) with pullover-style heat tube (PHT), the determination of heat tube diameter, calculation of enhancement of heat transfer, size and separation distance optimization of the radiator fin at the flue gas side. Expounds the calculation of heat transfer coefficient in the heat-release side and the influence of vapor speed on heat transfer of the tube. Proposes the calculation methods for parameters at both the heat-emission and the heat-release sides by thermal equilibrium theory.
