In the first place, with the comparison among several sorts of configurations between the ASU and gas turbine, EP-ASU is theoretically proved to have better overall IGCC power output, overall efficiency and net cost of power generation than LP-ASU.

• 具体来说，本文首先通过对空分系统与燃气轮机配置方案的深入研究和对比，从理论上说明了EP-ASU与LP-ASU相比能耗更低、投资更省、效率更高； 并进一步得出空分压比和空分系统的主冷温差是影响空分系统能耗的关键性因素。
