日本改进型联合循环发电机组介绍

Introduction to Advanced Combined Cycle Generating Unit in Japan

介绍日本改进型联合循环发电机组（ＡＣＣ）的工作过程、启动方式及内部能量流程，与其它发电形式相比，其热效率可达４９ ％ ，节能效果明显，符合环境保护要求。为进一步提高热效率，燃烧室温度将进一步提高，并对燃烧室和燃气轮机的材料进行改进。文章还对发展我国的ＡＣＣ 机组提出设想。

This article introduces the working process,start up scheme and internal energy flow process of advanced combined cycle generating unit(ACC) in Japan,indicates that,compared with the other power generation mode,its thermal efficiency may reach 49%,the energy saving effect is obvious,being up to the standard of environmental protection.For futher improving thermal efficiency,the temperature of combustion chamber will be further raised,and the materials of combustion chamber and gas turbine will be improved.Finally,the tentative ideas for developing China's ACC generating unit are put borward as well.
