【摘要】：本文在传统燃煤发电机组和氢氧联合循环的基础上,提出一种新型的氢氧-燃煤联合循环系统。该系统把超超临界燃煤机组与氢氧联合循环相耦合,实现了氢能和燃煤的高效利用,丰富了两种燃料的利用形式。本文使用EBSILON对该系统进行了初步模拟,研究结果表明,该系统在蒸汽初压为25.6 MPa,最高温度为1300℃时,发电效率可达到49.74%,并可通过提高循环最高温度和燃气透平膨胀比达到更高的发电效率。
[Abstract]:Based on the traditional coal-fired generator unit and the combined cycle of hydrogen and oxygen, a new type of combined cycle system of hydrogen, oxygen and coal combustion is proposed in this paper. The system coupled the ultra-supercritical coal-fired unit with the combined cycle of hydrogen and oxygen, realized the efficient utilization of hydrogen energy and coal, and enriched the utilization forms of the two fuels. In this paper, EBSILON is used to simulate the system. The results show that when the steam initial pressure is 25.6 MPA, the maximum temperature is 1300 鈩，
