燃用变成分气体燃料燃气轮机动力透平试验性能的计算及讨论

CALCULATION OF TEST PERFORMANCE OF A POWER TURBINE FOR VARIABLE COMPONENT GASEOUS FUEL-BURNING GAS-TURBINE GENERATING UNIT

一、前言 航机改型分轴式燃气轮机发电机组调试内容之一是正确取得为燃气发生器配用的新设计动力透平的实际性能。这种机组在调试过程中若燃用成分经常发生变化的气体燃料时,其性能和动力透平输出功率测量仪表的读数也会随之变化,从而会影响对动力透平性能的正确评价。若能用试验过程中量测剑的或每次调试前现场提供的燃料气成分。

This paper presents a method through a few test data. It is used in checking calculation of power turbine performance and its exhaust components as the components of gaseous fuel burned are variable during the operation. Also the influence of components variation of gaseous fuel and measurement error of static pressure on power turbine performance have been discussed.
