尾缘吹气式火焰稳定器试验研究

本文提出了一种新型火焰稳定器—尾缘吹气式火焰稳定器，它具有流线形头部，槽宽小，尾缘吹气并供油，不加力时流阻很小，加力时吹气扩大回流区，是一种机械与气动稳定结合的稳定器。对该稳定器进行了试验研究，得到流阻损失、贫熄边界、燃烧效率等性能的初步结果，表明该稳定器具有优越性，并有希望用于加力燃烧室。

EXPERIMENTAL INVESTIGATION ON EBMC FLAMEHOLDER

A novel flameholder is presented,as named Edge Blowing Mixture Curtain (EBMC) flameholder.It has a streamline form head,small base width,with air and fuel mixture flowing from the slots at it's edges into the main flow.It has small cold pressure loss without reheat and variable blowing on reheat so as to enlarge recirculation zone and improve combustion performance.An experimental investigation of this flameholder was carried out,and its pressure loss、lean flame blowoff range and combustion efficiency were researched.It seems that the EBMC flameholder is superior to the conventional V-type one.
