| Abstract: | A review literature concerning the heat transfer mechanism and its influencing factors are being presented, together with typical furnace heat transfer data and their dependence on relevant parameters. Taking circulating fluidized bed boilers of 12 MV,50 MW and 135 MW as examples, the heat transfer within the furnace as well as in the heat recovery zone is discussed together with the heat transfer of pendant heat delivery surfaces in the furnace of large circulating fluidized bed boilers and also in steam/water cold cyclone separators. Relevant empirical heat transfer coefficients are being listed. Figs 10,tables 2 and refs 12. |
