High-Temperature Heat-Shielding Panels with Thermochemical Cooling Based on the Reaction of Steam Conversion of Methane

A method is developed for thermohydraulic analysis of panel-type thermochemical reactors (TCR) with catalytic walls cooled by a gas mixture of methane with steam, in which an endothermal conversion reaction proceeds upon heating. The suggested method provides for all forms of heat transfer in the reactor, including the thermal conductivity of the metal frame in multichannel panels. The results of prediction study of the thermohydraulic characteristics and overall dimensions and weight of such reactors are analyzed.
