📄 Abstract（原文）
This paper proposes a novel hydrogen-oxygen-coal combined cycle system based on traditional coal-fired power generation units and hydrogen-oxygen combined cycles. The system couples ultra-supercritical coal-fired units with hydrogen-oxygen combined cycles, achieving efficient utilization of both hydrogen energy and coal, and enriching the utilization forms of the two fuels. A preliminary simulation of the system was conducted using EBSILON, with results indicating that at an initial steam pre...
