This paper presents the spectral reduction of the 1-D distributed dynamic model of a non-isothermal Circulating Fluidized Bed Combustor (CFBC). The continuum model is first approximated by a finite-difference method and integrated in time by means of Adams-Moulton method to provide a "reference" solution. Then, Proper Orthogonal Decomposition (POD) is introduced, coupled with a spectral penalty method, to derive a reduced order model (ROM). The penalty method deals with the variable boundary conditions which characterize the original model. The numerical performance of the proposed approach is evaluated
