Energy storage gas supply system

The invention provides an energy storage gas supply system, and belongs to the field of chemical engineering. The problem of non-uniform steam production of a matched boiler during chemical pipe network production is solved, and the steam boiler serves as a temporary standby steam source when the steam boiler trips out. The system comprises a plurality of steam energy accumulators, the water inlet end of each steam energy accumulator is connected with a water injection pipeline, the steam inlet end of each steam energy accumulator is connected with a steam energy charging pipeline, the condensate water outlet end of each steam energy accumulator is connected with a condensate collecting tank, and the steam outlet end of each steam energy accumulator is communicated with an exhaust pipeline; one inlet end of the steam mixing header is connected with the steam outlet ends of all the steam energy accumulators, the other inlet end of the steam mixing header is connected with a high-pressure steam pipeline, and th
