Sensitivity Analysis of Operation Parameters on High-Temperature Steam Generation of an Adsorption Heat Transformer
摘要
Abstract
A novel adsorption heat transformer with working pair of zeolite 13X and water for high-temperature steam generation from low-grade hot water and gas was experimentally studied. Effects of operation parameters on system performance under direct-contact heat exchange were investigated. The results show that COPh (coefficient of performance for heating) is raised by 24.45% when the feeding water temperature increases from 65℃ to 85℃. When the regeneration gas temperature increases from 110℃ to 150℃, the maximum steam temperature and gross temperature lift increase by 45℃ and 21℃, respectively.Meanwhile,the generated steam weight increases by 89.25%. The maximum steam temperature and generated steam weight are both enhanced via reducing drying gas humidity and increasing initial zeolite temperature,water feeding temperature and drying gas temperature. SHP(specific heating power) can be upgraded by increasing water feeding rate or appropriately decreasing drying time.关键词
