“…The heat exchanger designed in the present work is very similar to the one presented by Fischedick et al (2007), but its dimensions are much reduced, for the reasons already commented in the design objectives section. The heat exchanger is formed by ceramic plates that are stacked.…”

“…In the work of Fischedick et al (2007), the thermal design of the HTHE was conducted by using correlations for theColburn and friction factors for offset strip fins. These correlations were obtained from experiments by Manglik andBergles (1995).…”

“…One ceramic plate-fin HTHE was designed by Fischedick et al (2007) for 50kWth and many important design considerations were evaluated, such as: the choice of the ceramic material; structural integrity of the heat exchanger; thermal design; pressure drop introduced by the heat exchanger, and others that will be addressed in the present study. Pressure drop produced by the heat exchanger deserves special attention during design stage because it reduces the thermal efficiency of the cycle (Kautz and Hansen, 2007).…”

-There is a potential demand for heat exchangers capable of supporting working temperatures well above 900°C. Many different studies in the literature consider these components as critical for the implementation of externally fired gas turbines (EFGT) and externally fired combined cycles (EFCC). It is common sense that ceramics are the only alternative for the construction of these heat exchangers, but most part of the literature about heat exchangers usually considers only metallic materials for its construction. Consequently, the design of ceramic heat exchangers is not trivial and represents an actual technical challenge. In addition, different heat transfer modes are present simultaneously and as we all know that the geometry of heat exchanger decides the effectiveness of heat exchanger, two geometries are compared and discussed in this work. As a step in this direction, the present work presents the design of a ceramic heat exchanger using CFD and finite element structural simulations. The heat exchanger designed presents small dimensions in order to make it easier to construct a prototype and test it in the future.

“…Suzuki et al [35] studied the numerical and experimental analysis of the heat transfer and flow characteristics of a 2D flat plate arranged in a staggered manner used in mixed (free flow) convection region at low Reynolds number. Fischedick et al [36] experimented on heat recovery of a ceramic PFHE being used for heat exchanger applications. Peng et al [37] predicted the thermodynamic performance for longitudinal & transverse direction flow through the offset fins by a steady state, 3D numerical model.…”

“…From the above surveys (and even other ones, not reported here for brevity), it results that the most promising architecture for gas-to-gas heat exchangers working at high temperature makes use of an intermediate thermal medium (ceramic material) first to recover and then to release heat from one flow to another one. However, to the authors' knowledge, the largest ceramic heat exchanger proposed so far by SchulteFischedick et al [8], weighing up to 4 t, refers to a 6 MWe plant. In a recent work, McDonald [9] examined a wide range of heat exchanger concepts and demonstrators able to fulfill some of the aforementioned requirements; its cost-effective approach recognized the potential of ceramic recuperators for microturbines.…”

This paper proposes the design of an innovative high temperature gas-to-gas heat exchanger based on solid particles as intermediate medium, with application in medium and large scale externally fired combined power plants fed by alternative and dirty fuels, such as biomass and coal. An optimization procedure, performed by means of a genetic algorithm combined with computational fluid dynamics (CFD) analysis, is employed for the design of the heat exchanger: the goal is the minimization of its size for an assigned heat exchanger efficiency. Two cases, corresponding to efficiencies equal to 80% and 90%, are considered. The scientific and technical difficulties for the realization of the heat exchanger are also faced up; in particular, this work focuses on the development both of a pressurization device, which is needed to move the solid particles within the heat exchanger, and of a pneumatic conveyor, which is required to deliver back the particles from the bottom to the top of the plant in order to realize a continuous operation mode. An analytical approach and a thorough experimental campaign are proposed to analyze the proposed systems and to evaluate the associated energy losses.
