	abstract = {Radical changes have been happening on the source side of the electricity system due to the rolling back of large-sized fossil-fueled power plants and the coming to the front of uncontrollable renewables. As a worldwide consequence, to ensure the permanent balance of the grid, even big-sized units have to be operated in load- following mode, including also nuclear power plants. This mode is conducted by the control system, which must also consider the side effects of this rather dynamic operating mode. In this report, we show up all components of such a control system, including the process model, structural integrity assessment, and control algorithm. All the above elements are discussed on the basis of a concrete example, and the resulting control behavior of the entire system is also shown. The results demonstrated that a significant reduction in the caused thermal stresses could be achieved while keeping the control quality practically unchanged.},

	abstract = {Life cycle assessment of utility power plants confirms that a significant and nearly unchangeable portion of their ecological footprint is generated at the beginning and end of their lives. This is especially valid for nuclear and renewable power plants with practically zero CO2 emission during operation, and also for other, traditional power plants. This is why extending the lifetime of such power plants directly and markedly contributes to climate change mitigation. Let us consider that material ageing seems to be a major cause of limited lifetime in dominant power plants. Let us also note that it is mostly affected by mechanical and thermal stresses, which are strongly influenced by the control system, the effect of which is sharpened by the load-following operation. Although the control theory offers excellent tools for handling such complex systems too, their practical applications in power plants are still on a very low level because of insufficient engineering background on plant operation, process engineering, and material ageing. The current work, summarized in this chapter, integrates all the above disciplines, starting out from the practical plant requirements and properties, extended towards an application-oriented review of matured advanced control methods. Further, a very advantageous, generally applicable structure will be outlined, which includes online (fast acting, local) and offline (more detailed, remote) modeling and control elements. Additionally, as the proposed method also improves plant efficiency, it simultaneously contributes to higher financial benefit and lower emission.},

	abstract = {The utilization of challenging solid fuels in the energy industry (especially the ones derived from wastes) has a big priority nowadays, as it is a valid option to keep the recent EU directive related to the decrease of landfills. However, there are serious technical challenges, connecting to the lack of knowledge about the behavior of these fuels in the combustion chamber. This paper discusses the specific aspects of developing particle models concerning the combustion of these non-conventional fuels. A new modeling approach is presented, using which it is possible to develop an all-round particle model that includes every significant influencing process. Moreover, it does not have any restrictions regarding the shape, size and the origin of the particle. As an integral component of this model, the distinctive aspects of intrinsic reaction kinetics related to waste fuels are presented as well.},

	abstract = {Two approaches are commonly used for modeling the vertical mixing of binary-mixture fluidized beds, Computational Fluid Dynamics (CFD) and macroscopic modeling. A common realization of the latter one is the Gibiralo-Rowe (G-R) model, which uses the Two-Phase Theory. This macroscopic model obviously overperforms CFDs regarding computational cost; however, determining its coefficients is a still challenging issue. Although several methods were published for solving this, the general problem with most of them remains their neglecting the conservation of mass. In the present new procedure, the mass conservation is applied to correct the values of the G-R model coefficients estimated from known equations. The present model was validated on a wide variety of fluidized bed systems. The results show that this conservative and macroscopic model gives more accurate predictions than the recently published other macroscopic models, and this one is, in general, better than the CFD model from the perspective of prediction accuracy as well.},
