System and method for coupling saturated steam generated by green electricity heating with steam generated by boiler

The invention relates to a system and a method for coupling green electricity heating saturated steam generation with boiler steam generation, the system comprises a green electricity heating saturated steam generation subsystem and a boiler steam generation subsystem, the boiler steam generation subsystem comprises a boiler barrel and a steam overheating treatment unit, the green electricity heating saturated steam generation subsystem is used for connecting green electricity and converting electric energy into heat energy of saturated steam, a saturated steam channel and a saturated steam channel of the boiler barrel are converged and then jointly communicated with the steam overheating treatment unit, and a boiler supplementary combustion subsystem used for increasing the smoke amount is arranged in the steam overheating treatment unit. Therefore, the influence of saturated steam generated by the electric heating saturated steam generation subsystem on the saturated steam of the existing boiler barrel can
