Abstract

The invention discloses a steam generation system based on SOEC and a control method thereof. The steam generation system based on SOEC comprises a water storage tank, a magnetic pump, a pressure-proof water tank, a liquid mass flowmeter and a steam generator; the water storage tank, magnetic pump, the pressure-proof water tank, the liquid mass flowmeter and the steam generator are connected in sequence through pipelines; a steam outlet of the steam generator is connected with a steam transmission pipeline, the generated steam is sent to a subsequent steam consuming unit; an electromagnetic regulating valve a for regulating the flow rate is arranged between the magnetic pump and the pressure-proof water tank; a coupling solenoid valve for regulating the flow rate is arranged between the liquid mass flowmeter and the steam generator; the steam transmission pipeline is separately connected with the steam consuming unit and an emptying pipeline, and a connection point is separately provided with a shut-off valve A and a shut-off valve B for pipeline opening and closing

Description

technical field [0001] The invention relates to the field of solid oxide electrolysis technology (SOEC), in particular to an SOEC-based steam generation system and a control method thereof. Background technique [0002] Hydrogen has attracted more and more attention due to its advantages of cleanness, high calorific value, large raw material reserves, and rich application scenarios. There are no pollutants in the product and process of hydrogen production, which is a clean hydrogen production method. [0003] At present, there are mainly alkaline electrolysis technology, solid polymer electrolysis technology (SPE) and solid oxide electrolysis technology (SOEC) for electrolysis of water to produce hydrogen energy storage technology. Alkaline electrolysis technology is the most mature and the lowest cost, and has achieved large-scale hydrogen production applications, but the efficiency is low. Hydrogen production by SPE electrolyzed water is suitable for the application of f...
