Regenerative high temperature steam production

The operational principle of high temperature pressured steam generator was introduced in this paper. The experiments of high temperature steam production were performed with a high temperature steam generator during different periods with the range of 20-200 s. Temperature variation of high temperature steam and exhaust gas for different switching periods and that in a single switching period were studied. The efficiency of temperature and heat recycle was also investigated. Temperature fluctuation increases with the increase of switch time. At the same exhaust gas temperature, the increased switch periods lead to the decrease of temperature efficiency. The results show that the steam efficiency of heat recycle reaches the maximum with the switching period of 60 s. The exhaust gas temperatures remain within the range of 180-200°C for different switch periods.
