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.
