Energy storage and steam generation system and method

An energy storage and steam generation system, comprising an electrode steam boiler (1), wherein one side of the electrode steam boiler (1) is connected with a boiler deaerator (2) through a pipeline;

• a pipeline A (3) is arranged at the top of the electrode steam boiler (1);
• the pipeline A (3) is connected with a steam superheater (4);
• an outlet of the steam superheater (4) is provided with an external steam supply outlet pipeline (5);
• a molten salt steam generation bypass pipeline (6) and a pipeline B (7) are arranged on the steam superheater (4);
• one end of the molten salt steam generation bypass pipeline (6) is connected to the steam superheater (4);
• a low-temperature molten salt storage tank (8) is connected to the pipeline B (7);
• a high-temperature molten salt storage tank (9) is connected to the low-temperature molten salt storage tank (8) through a pipeline;
• the other end of the molten salt steam generation bypass pipeline (6) is connected to the high-temperature molten salt storage tank (9);
• a water supply bypass pipeline (10) is arranged on a pipeline section between the electrode steam boiler (1) and the boiler deaerator (2);
• one end of the water supply bypass pipeline (10) is connected to the pipeline section between the electrode steam boiler (1) and the boiler deaerator (2);
• the other end of the water supply bypass pipeline (10) is connected to the pipeline A (3);
• a feed water pump (11) is arranged on a pipeline section between an inlet end of the water supply bypass pipeline (10) and the boiler deaerator (2);
• a preheater (12) and a steam generator (13) are sequentially arranged on the water supply bypass pipeline (10);
• the molten salt steam generation bypass pipeline (6) also sequentially passes through the preheater (12) and the steam generator (13);
• a molten salt bypass pipeline (14) is arranged on the molten salt steam generation bypass pipeline (6);
• and each of the preheater (12) and the steam generator (13) are disposed at a pipeline section between an inlet end and an outlet end of the molten salt bypass pipeline (14).
