A method is proposed for predicting heat transfer coefficients in hot fluidized-bed combustors by translating results measured in a scaled-down, cold model bed. Provided the beds are scaled to hydrodynamic similarity, local heat transfer coefficients measured in the cold model bed can be translated into local hot-bed convective coefficients with the aid of existing correlations for the gas and particle convective components.
