Thus, the electric boiler is always in a hot standby state when the single unit is operated. There are several problems with this state: firstly, an electric boiler is started slowly, the steam generating speed is low, 18 minutes are required for generating qualified steam at the highest speed, the shaft seal steam supply requirement during the steam turbine is not met, and when the emergency shutdown is carried out, the residual steam of the system is utilized, so that the external shaft seal steam supply time is required to be not more than 10 minutes; secondly, the steam parameters are low, the temperature is 220 ℃, the pressure is 2.0MPa, the steam parameters are almost constant, the adjustment is impossible, the steam is nearly saturated, and the shaft seal steam temperature above 320 ℃ can not be reached; thirdly, the operation stability requirement of the electric boiler is higher; finally, the electric boiler is always in a hot standby state, and the power consumption is high. The existing energy storage type steam generation system can rapidly and timely provide the superheated steam with the temperature of more than 300 ℃, solves the problems that the starting time of an electric boiler is long, the temperature of the electric boiler cannot reach the temperature requirement of the superheated steam with the temperature of more than 300 ℃ of shaft seal steam, provides reliable and stable steam for the shaft seal, and ensures the safe shutdown of a steam turbine. The heat exchange tube of the novel single-tank high-temperature energy storage steam generator 202021738615.1 has the effect of preventing the heat exchange tube from being corroded on the outer wall of the energy storage tank, but has the defects of high processing and assembling process difficulty, low heat exchange uniformity, low heat transfer coefficient and the like, and the temperature difference between the inlet water temperature of the heat exchange tube and the temperature of a pipe is generally not more than 50 ℃, so that the outlet steam temperature of an evaporator is limited. The patent discloses a shaft seal steam supply system 202023218118.1 with an energy storage function, mainly referring to a system for storing energy and supplying the shaft seal, and not referring to an energy storage type evaporator structure and system.
