摘要: Abstract In order to achieve the energy cascade utilization and improve efficiency of coal–water–slurry (CWS) gasification for hydrogen system, heat integration scheme (HIS) between water gas shift unit is put forward. The effects temperature change CWS oxygen on performance are investigated. Both HIS non-heat (NHIS) analyzed by using performance, conversion exergy efficiency. results show that specific coal consumption decrease 2.7% 6.5%, respectively, as feedstock preheated up 150 °C. NHIS nearly same. (62.66%) better than (62.02%). Therefore, WGS unit.
