Study on characteristics of regenerative high temperature air production
蓄热式高温空气制备特性研究

The hot experiments of high temperature air production in different and single switching periods were carried out on the high temperature pressured steam generator. The temperature efficiency and heat recycle efficiency were computed for different switching periods. The results showed that the optimal switching period of air preheat was 30 s. The temperature efficiency and heat recycle efficiency decreased as the switching period increased. In one switching period, the air preheating temperature declined with heat exchange time prolong. The exhaust temperature was low and it showed that the heating absorption of the regenerative porous ceramic was good.
