ABSTRACT OF THE DISCLOSURE The current invention concerns a combustor having a coupling for a cross-flame tube. The coupling has inner and outer sleeves that form an annular passage therebetween. Holes in the outer sleeve place the annular passage in flow communication with cooling air in the combustion system chamber, thereby causing the cooling air to flow over the proximal end of the outer sleeve. A baffle is formed on the inner sleeve and has a pattern of raised and depressed areas. The raised areas form lands that are attached to the combustor wall. The depressed areas form passages with the wall that direct the cooling air from the annular passage so that it flows over the surface of the combustor inner wall, thereby preventing over heating of the wall.
