| Abstract: | A type of compact plate_fin reactor with inner heat exchangers for sulphur dioxide conversion was proposed. Heat transfer and resistance properties of this reactor with different fin scales are experimentally studied. It is found that heat transfer coefficient increases with fin height, while flow resistance varies as concave curve, that is to say, the resistance reaches the lowest value at a middle fin height. This flow phenomenon is analyzed through numerical calculation in this paper. |
