METHOD AND SYSTEM FOR CO-PRODUCING STEAM IN POWER GENERATION PROCESS

WIPO Patent Application WO/2024/027073

A1

A system for co-producing steam in a power generation process, which comprises a fuel cell, a gas supply unit, an oxygen supply unit, a first steam generation unit and/or a second steam generation unit. In the system, the fuel cell uses a fuel gas provided by the anode of the fuel cell and oxygen provided by the cathode of the fuel cell to carry out power generation reaction and produce an anode tail gas and a cathode tail gas. The anode tail gas exchanges heat with water at the first steam generation unit to generate steam, and the cathode tail gas exchanges heat with water at the second steam generation unit to generate steam, so as to realize heat-power co-production. The invention combines fuel cell power generation with the steam production process, utilizes cheap resources such as industrial purge gases and refinery tail gases as the fuel gases of the fuel cell for power generation, and then utilizes heat of the tail gas of power generation to produce steam, thereby improving the residual heat quality of the fuel cell and saving natural gas resources.
