Mass transfer in thermochemical solid/gas reactor for thermal storage applications

Résumé

Solid/gas thermochemical processes are promising systems for high density thermal storage purposes (200 to 500 kWh.m-3). Two very different applications are analyzed: low temperature storage using SrBr 2 /H 2 O pair for space heating (80°C), and high temperature storage (500°C) using CaO/H 2 O pair for thermodynamic solar power plants. Mass transfer is a key issue for such high density beds. Thus, their permeabilities were investigated. For SrBr 2 /H 2 O beds, experimental and correlation-based studies highlighted the strong influence of bed energy density and reaction advancement on permeability and give the order of magnitude of these variations. For CaO/H 2 O beds, similar correlations allowed predicting the bed permeability variations. Experimental studies are in progress.
