Abstract

1,213,215. Gas turbine combustion apparatus. MINISTER OF TECHNOLOGY. June 4, 1969 [June 10, 1968], No. 27395/68. Heading F1L. A flame stabilizing device, e.g. for the reheat or bypass duct of a gas turbine engine, comprises a vane of generally aerofoil cross section having recesses 7, 8 in which flow recirculation zones are set up. The length of the recesses 7, 8 in the direction of flow is such that the velocity at the periphery of the recirculating flow is less than that of the main gas flow over the vane so that some mixing of the flows occurs. Fuel is supplied through nozzles 18, 19. In the arrangement shown the nose portion 14, of the vane is hollow and has an upstream opening 15 through which cooling gas from the main stream flows. The gas leaves the vane through openings 16,17 to flow over the surfaces of the solid rear portion 13. The surfaces of the recesses 7, 8 may be formed from a refractory ceramic such as silicon nitride. In a modification, opening 15 may be dispensed with and the cooling gas supplied from some other source. In further modifications, Figs. 1, 2 (not shown), the vanes are solid, the recesses (2, 3) in Fig. 1 having an elliptical shape.
