摘要

概述了某重型燃气轮机燃料喷嘴组流量试验研究结果。为了测量该喷嘴组各流路供给的燃料气流量

专门研制了SH-1型气体流量试验器

其测量流量准确、稳定、重复性好

造价仅为同类设备的五分之一。应用SH-1型试验器准确地测量了喷嘴组流路Ⅲ、Ⅳ、Ⅴ供气流量

分析喷嘴组加工、焊接等工艺对喷嘴组各流路流量的影响规律

在此基础上进行了火焰筒单管燃烧试验。结果表明

喷嘴组各项指标均达到设计要求

燃烧室出口温度分布系数小于10%

沿叶高径向温度分布合理。

Abstract

The test and research results of the flow rate for the fuel injector group in a heavy-duty gas turbine have been expatiated.In order to measure the fuel gas flow in every branch in the fuel injector group

a SH-1 type testing device of gas flow rate has been specially developed.The said testing device has accurate stable performance and good reproducibility

and its cost is onlyfifith of that for the similar type instrument.By using said testing device

the flow rate of Ⅲ

Ⅳ

Ⅴ branches in the fuel injector group has been accurately measured

and the influence of technological process in fabrication and welding etc.upon the flow rate in a combined flow passage being analysed

and a combustion test of the injector group being made in a simple flame tube.Results show that the index in each item all meet the designed requirements

the radial temperature distribution coefficient at outlet of combustion chamber is less than 10%

the radial temperature distribution along the direction of blade height being resonable
