The invention relates to a heat storage and energy saving process for intermittent heat release and continuous heat application. The process comprises the following steps that (1) high-temperature medium generated by an intermittent heat release device enters a heat exchanger through a draught fan or the pressure of the medium itself, low-heat high-temperature aqueous medium enters the heat exchanger through a high-temperature water delivery pump, and after indirect heat exchange is carried out on the high-temperature aqueous medium and the high-temperature medium, medium after heat release, high-heat high-temperature aqueous medium and exhaust gas are obtained respectively; the medium after heat release returns to the intermittent heat release device; and the exhaust gas is discharged from the system; (2) the high-heat high-temperature aqueous medium firstly enters a heat storage device and then enters a heat generation device, fresh water enters the heat generation device to generatesteam and low-heat high-temperature water respectively through flash evaporation and heat release; and the steam enters the next process; (3) the low-heat high-temperature water enters the heat exchanger again through the high-temperature water delivery pump. The heat storage and energy saving process for the intermittent heat release and continuous heat application has the advantages that the investment is small, the implementation is easy, and the operation cost is greatly reduced.
