The study of the phenomena in fluidized beds has a great importance for the knowledge and development of FBC technologies. But nowadays, and from an operational point of view, the interest lies not only in fluidized bed behavior, but also in the influence of fluidized bed variables in the rest of the power plant. Although there is a great variety of designs and studies on FBC power stations (AFBC, CFBC and PFBC, with different types of cycles and first and second generation fluidized beds), there is a lack of detailed studies considering the interactions between the bed variables and the performance of the cycles (steam and gas). In order to improve the knowledge from this particular standpoint, an integrated model of the Escatron PFBC 80 MWe power plant (Spain) has been developed. The model has been validated with actual plant data, being able to predict the behavior of the plant as a whole. To do this, it estimates the most important variables of the fluidized bed (i.e., bed temperature profiles, bed density, fuel feed rate, heat transfer, entrainment, gas and steam flow rates), as well as the operating parameters of the power cycles (i.e., steam and gas turbine loads, temperatures and pressures). A practical application of this model is the evaluation of operational and design changes affecting the response of the fluidized bed, the steam and gas cycles, and, in turn, the power plant efficiency and availability.
