Title:

SYSTEM AND METHOD FOR HYDROGEN AND POWER COGENERATION OF COAL-FIRED BOILER

Document Type and Number:

WIPO Patent Application WO/2023/202139

Kind Code:

A1

Abstract:

The present disclosure provides a system and method for hydrogen and power cogeneration of a coal-fired boiler. The system couples a coal-fired boiler, sulfur-iodine circulating hydrogen production, and supercritical carbon dioxide power generation for hydrogen and power generation. The system comprises a coal-fired carbon dioxide boiler, a carbon dioxide power generation system, a high-temperature heat exchanger, and the like. According to the present invention, an iodine solution is used for absorbing sulfur dioxide in the boiler flue gas, extra carbon dioxide emission cannot beThe present disclosure uses an iodine solution to absorb sulfur dioxide in the boiler flue gas, so that additional carbon dioxide emissions cannot be generated, iodine can be recycled, and the operation cost is low. The polluting gas sulfur dioxide generated from the boiler is used for hydrogen production, reducing pollution and increasing energy. The supercritical carbon dioxide power generation works at a temperature range for the highest efficiency, improving the power generation efficiency.
