中文摘要：
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。
英文摘要：
Based on the traditional coal fired power plant and H_2/O_2 combined cycle,this article presents a novel H_2/O_2- coal fired combined cycle.Because of a high degree of coupling of ultra-super critical coal fired power plant with H_2/O_2 combined cycle,the novel cycle provides an efficient approach for using coal and hydrogen,which enriches the forms of fuel utilization.In this paper,the software EBSILON professional is used for system simulation.Research shows that the net energy efficiency of the novel cycle can reach 49.74%with the parameters of the live steam of 25.6MPa/1300℃.As the maximum temperature of the cycle and the pressure ratio of the gas turbine enhance,the greater energy efficiency can be achieved.
