摘要

本文在燃气轮机燃烧室中研究了乙醇/煤油作为混合燃料工作时,文氏管表面的碳沉积性能。RP-3煤油与乙醇的混合燃料中乙醇的比例按重量计分别为0%、10%、30%和50%。碳沉积试验在3个大气压的单头部燃烧室内进行,每种燃料燃烧一个小时。文氏管作为旋流杯空气雾化喷嘴的部件,其特殊的结构使得测量碳沉积非常困难。本研究通过平面重建的图像处理方法,半定量的评估了文氏管表面的碳沉积量。并使用扫描电镜观察了不同试验燃料下的碳沉积形态和结构。试验结果表明,随着乙醇添加量的增加,文氏管表面碳沉积量减少,碳形态发生显著变化。在纯煤油的情况下,文氏管表面紧密地交织着瘤状体和鳞片石墨。对于其他混合燃料,没有观察到瘤状体,鳞片石墨整齐地堆叠并排列在文氏管表面。这些结果表明,乙醇的加入显著改变了积碳的形态和结构,由于燃料分子结构的变化,积碳机理已经发生变化。

Abstract

This paper reports an investigation of carbon deposition on the venturi component of a gas turbine combustor fueled with ethanol/kerosene fuel blends. China RP-3 kerosene and its ethanol blends (10%, 30%, and 50% ethanol by weight) were used in a gas turbine model combustor. Each combustion test of carbon deposition was conducted at 0.3 MPa for an hour. Measuring carbon deposition became difficult because of the special structure of venturi which is a component of swirl cup air atomization nozzle. An image processing method called planar reconstruction, was developed to evaluate the amount of carbon deposition semi-quantitatively. To study the morphology and structure of the deposition for different test fuels, a Scanning Electron Microscope (SEM) was employed to visualize the detailed structures of carbon deposition. Results show that with the increasing addition of ethanol, the amount of carbon deposition decreases, and the morphology of carbon changes significantly. For pure kerosene case, small spherules and flake graphite were closely interwoven on venturi surface. For other fuel blends, small spherules were not observed, and flake graphite neatly stacked and lined on the venturi surface. These results indicate that the mechanism of carbon deposition can vary significantly, due to the change of fuel’s molecular structures; the current study shows that the morphology and structure of carbon deposition of kerosene were altered remarkably by the ethanol addition.
