透平冷却空气冷却系统及其对燃气轮机联合循环的影响分析

摘要

对通用、西门子和三菱F级燃气轮机透平冷却方式的比较，三菱M701F4燃气轮机透平的冷却方式更为特殊复杂，通过透平冷却空气冷却系统（TCA系统）进一步冷却，然后再送往透平做冷却空气用。本文对TCA系统进行介绍并分析对燃气轮机联合循环机组发电效率和余热锅炉系统影响。%Compared to General Electric, SIEMENS and MITSUBISHI F level gas turbine cooling system, MIT-SUBISHI M701F4 gas turbine cooling system is more complicated. After being cooled in TCA system, the air is sent to the turbine and as cooling air. The TCA system is introduced and analyzed. The influence to gas turbine combined cycle unit generation efficiency and waste heat boiler system is analyzed.
